While I agree with you Conner, when I did a survey for piglit I found that OSX was the only major OS that didn't provide a python2 symlink, Arch, Gentoo, Debian, Fedora, and CentOS all did, and Windows doesn't care about a shbang. I would actually be in favor of using /usr/bin/python2 anyway, just because it makes it clear we're using python2, but ultimately you're right and it doesn't really matter. It's also been on my todo list to get all of the python in mesa working with both python2 and python3, but I have too many things to get done.
