[PyMOL] Pymol + Freeglut --> internal error

[Derek A. T. <der...@gm...>]

Hi all,

I am developing a crystal-generator and MD simulation debugger running
through pymol. It works pretty well on my primary computer, but I hit a bit
of a snag when one of my two computers refuses to run pymol. I am using
freeglut with pymol. I was easily able to get this to work on a OSX
10.7.3 macbook pro (core i7 cpu). However, after doing the same series of
steps to install everything on an iMac with the same OS (core i3 cpu), I
get the following error when starting up Pymol:

freeglut (pymol):  ERROR:  Internal error <visualInfo could not be
retrieved from FBConfig> in function fgOpenWindow

I haven't been able to find much information on this error and was
wondering if anyone had any experience with this. Have I not installed it
properly? Is there another alternative to freeglut that might work? I would
be very grateful for any help I can get.

For further information, I performed both 1) a complete installation from
source of freeglut and pymol AND 2) installed from a clean (empty)
MacPorts, but both methods resulted in the above error when running Pymol.
This error only occurs on the core i3 iMac. The GPU of the macbook is an
AMD Radeon HD 6750M (+Intel HD Graphics 3000) while the iMac is an ATI
Radeon HD 5670.

Of course, the precompiled 1.3 version of pymol that I have does run find,
but I am interested in using 1.5 on x11.

Thank you in advance for any thoughts or advice.
