[MINC-users] x86 system optimization

[Jason Lerch]

Jon,

ldd only lists dynamically loaded libraries - it is therefore possible 
that Rick compiled Display using a static version of Mesa. There is no 
way, however, that Display can run without some version of OpenGL or its 
predecessors (that I know of, anyway).

Cheers,

Jason
