Brandon, Thanks very much for all this information about Mathematica - that gives me a glimmer of hope!

I looked in the "/usr/local/Wolfram/Mathematica/5.2/SystemFiles/Libraries/Linux" directory, and this is what it contains for me: libguide.so libgmp.so.3 libvml.so libmkl.so libmkl_def.so libmkl_lapack32.so libmkl_lapack64.so libmkl_p3.so libmkl_p4.so libmkl_p4p.so libmkl_vml_def.so libmkl_vml_p3.so libmkl_vml_p4.so libmkl_vml_p4p.so Are these names familiar to anyone? Are these Qt libraries or are there others too?
