Hi Marius,

So I grabbed Pymol through macports, but now the main control window isn't being rendered.  I also receive the following error message. I've truncated the error message.  I know that macports resolved the tk/tcl dependencies, so I'm not sure what's up?  Has anyone else run into this problem?

Did you try the macports (http://www.macports.org/) version?

Hi gang,

Actually, I spoke too soon! I attempted this compilation to address another user's problems with an external script. But as you can see from the attachment, the main control window is not being rendered properly.  Am missing other libraries?

Hi gang,

Just wanted to share some notes on compiling and getting Pymol 1.3.x running on OS X Snow Leopard. Before proceeding, you'll of course need the XCode SDK which comes supplied with the OS X cd's or downloaded through apple's developer site.

(1) Compilation:

For some reason, the included freetype2 library is insufficient even though the compilation flags correctly point to the library's path (ext/include/freetype2).  The compilation fails with the following message (truncated):

In file included from layer1/TypeFace.c:25:
/usr/X11R6/include/ft2build.h:56:38: error: freetype/config/ftheader.h: No such file or directory

The fix is to prepend the build step with the following CFLAGS environment variable like so which points to the system default X11 library:

CFLAGS="-I/usr/X11R6/include/freetype2" python setup.py build

You can then proceed with the installation, followed by the secondary setup2.py commend as noted at the end of the build step. 

(2) Additional library:
A required library, Pmw,  isn't included with the SVN trunk, so you'll need to download it from the following site:

Unpack; dive into the src folder and issue 
python setup.py build
python setup.py install

All should work.
