Hmmm ... I can compare GL headers on both machines but 
querying pointers should not be needed when using core API.

Anyway, even with querying function pointers libGL.so should contain
string "CreateProgram", is that right?  When I extract all strings (i.e
not just linker symbols) from libGL.so (using 'strings' program) there's
no such string.
