Comment 7 for bug 77383

mesa-swrast-source seems to have been replaced by mesa-swx11-source, so I've updated the Build-Depends. Also killing the build were a few bashisms in debian/rules. I've fixed them, and tested it (I made the mistake of thinking that if the changes worked in Dapper, they'd work in Edgy too; of course, I overlooked the fact that it had never built in Edgy, sorry). It works, and isn't vulnerable.
