I figured out the issue - somehow Wine's trying to load the wrong libGL.so. I went in and changed the links like so. Code: sudo rm /usr/lib/x86_64-linux-gnu/libGL.so sudo ln -s /usr/lib/nvidia-current-updates/libGL.so /usr/lib/x86_64-linux-gnu/libGL.so and now my git build runs fine (the package from the repos still threw an exception, oddly - though it didn't have the GL error any longer). It may be possible to get around this by just using a preload. I had tried it earlier, but without success. Steffie - Can you direct me to the discussion on launchpad so that I can see if I can do anything to help them troubleshoot? I went looking for it, but was unable to find it.
