Hey,
I'm a long time user of macports, but recently I have decided to check out
homebrew for a number of reasons. Currently there is no standard way to
install pymol with this technique, but I thought it should be possible. I
set out to install pymol from source without the MacPorts libraries that
had helped me before.
I had significant trouble installing the current stable tarball. After
serious alterations to the setup script and some header files, I finally
got it to compile the cmd library, but any time I tried to load it with
python I had an error saying that it could not find the symbol
`_glutswapbuffers`.
Clearly some of this was a known issue because many of these changes were
addressed in the most recent trunk/head of the svn repository. I had to
make a few minor changes to make sure that it supports non-MacPorts
installations (https://gist.github.com/4267806), but it was rather trivial.
With this, I could install given I had Xquartz installed and a few other
dependencies. I created a homebrew repo that takes advantage of this change
here:
https://github.com/scicalculator/homebrew-pymol
Using the above, you can successfully install pymol using homebrew. The
only problem ... the toolbar fails to function. It does not throw any
errors if you have Pmw installed, but the toolbar widget never shows
itself. I have dome some other testing (https://gist.github.com/4269280) to
see if I can get the toolbar to show up, but no luck.
Does anyone have any hints as to where to look to get passed this part.
Also, if you have any ideas on fixing the `glutswapbuffers` error on the
"stable" branch, I'd love to hear it. Anyway, I hope this helps any users
of homebrew out there.
