Re: [PyMOL] PyMOL doesn't start - weird problem with shaders

Hi Thomas,

thanks a lot, good to know that it's not just me, I was getting mad
over this. I have opened a ticket at macports and put you in cc in
case you'd like to follow the issue (
https://trac.macports.org/ticket/42860 ).
Talking about macports, just for you and everybody on the list to
know, I have adapted the 1.6.0 patches to work for version 1.7.1 (
https://trac.macports.org/ticket/42860 ). I've been using this version
for few months now and looks fine to me, and may be helpful in case
anybody needs a more recent PyMOL on macports. Just don't update it
right now or everything will screw up :) let's hope this gets fixed
quickly.

Thanks again for your help

Matteo
