MacPorts on Snow

MacPorts on Ice?

the move from Leopard to Snow Leopard can be slippery

... emacs-app won't compile; different versions of python fall over each other; NLTK won't build ...

Here are some tips others have found helpful:

try

% sudo port selfupdate
% port installed
% sudo port uninstall installed

sudo port selfupdate

brings your MacPorts installation up to date. If this fails you should just start over

port installed

shows you what you currently have installed.
Much of what you see you won't recognise as this also lists the prerequisites installed to support the things you asked for explicitly.

sudo port uninstall installed

removes all your installed ports

or just start over

I had some problems when I moved to snow leopard, so I also removed all trace of macports

sudo rm -rf /opt/local \
/Applications/MacPorts \
/Applications/DarwinPorts \
/Library/Tcl/macports1.0 \
/Library/Tcl/darwinports1.0 \
/Library/LaunchDaemons/org.macports.* \
/Library/StartupItems/DarwinPortsStartup \
/Library/Receipts/MacPorts*.pkg \
/Library/Receipts/DarwinPorts*.pkg \
~/.macports

then reinstall MacPorts

use the Snow Leopard MacPorts disk image

then do

% sudo port selfupdate

check

which ports are available for snow-leopard? before you decide which ports to install.

% sudo port install  <????>

sudo port install <????>

will install whatever you specify
<????> should be a space- separated list of port names,
with no <   >

There is a problem with emacs-app—and we can't work without emacs...

install emacs-app

To install emacs-app, first download emacs-app-Portfile-snow-leopard.patch
and
emacs-23.1-snow-leopard.patch

% sudo port clean emacs-app
% sudo port install emacs-app
% cd $(port dir emacs-app)
% sudo patch -p0 < ~/Downloads/emacs-app-Portfile-snow-leopard.patch
% sudo cp ~/Downloads/emacs-23.1-snow-leopard.patch ./files/
% sudo port -D . install

Works for me, but your mileage may vary ....

Uninstall SPSS

installer tells me that a there is still a previous version of SPSS 16 on my mac

SPSS is great, but ...

The Mac install is clunky. If you've aborted an install and want to start again, or you just want to get some space free, you have to remove the old installation.

You've removed all files and directories matching *spss* (and, for good measure, youve also tried *SPSS*), and you can't start again because the installer complains that you haven't removed a previous installation.

remove InstallShield (probably sitting in your home directory) and start again!

If you want to get rid of an older version, and you haven't yet started, use the uninstaller installed with SPSS,

SPSS know about the problem

They say:

Problem Subject: Trying to install SPSS 16 for the Mac yields an error message that there is already a previous flavor

Problem Description: I am trying to re-install SPSS 16 for the Macintosh and I am unable to do so because during the installation I am met with an error message telling me that there is already a previous flavor of SPSS on this machine and that it must be removed before a new install can take place. What is the reason for this message and how can I resolve this so that I can install SPSS 16 for the Macintosh?

Resolution Subject: Completely remove the previous installation of SPSS 16 from this machine

Resolution Description: The reason this is happening is that the previous installation of SPSS 16 for the Macintosh was not uninstalled correctly. If you merely trashed the application folder then SPSS 16 was not uninstalled. The uninstall function is found with the SPSS 16 applcation in the 'Applications' folder. In order to resolve this issue if SPSS 16 is not removed through the uninstall process please go into the 'Users' folder on the main operating systems hard drive. In here you should find a house with your login name on it and you should go into this item. In this house (folder), please trash the following:

~/initspssmac

~/InstallShield (directory, remove the whole thing)

~/Library/Preferences/com.spss.spss for mac.plist

Now empty your trash. Now you will be able to re-install SPSS 16 for the Macintosh.

polyml

Dave Matthews's polyml is my implementation of choice for Standard ML (my language of choice).

The latest release (version 5.1) compiles on Leopard. The download should be unpacked automatically by Stuffit Expander—otherwise use gtar xvzf polyml.5.1.tar.gz.

cd polyml.5.1
./configure
make
sudo make install

You should get the message:

Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable
     during execution

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

You can also download later development versions of the source from the cvs repository on sourceforge:

cvs -d:pserver:anonymous@polyml.cvs.sourceforge.net:/cvsroot/polyml co polyml
cd polyml
cvs update -Pd
chmod +x install-sh
./configure
make
sudo make install
