I think the best thing you can do is go to a forum, ml or faq that has
explicit instructions on how you use this library. From looking at the
symbol name sit would appear that you have missed one library, one of the
GL(UT) ones maybe, I don't know. Go through the libraries that MESA
installed and see what gl* ones you've missed out.
