No, but I guess that's not the place to do it since they are unrelated 
to DOLFIN and just produce a foo.pc file.

I guest the right way is to use 'pkg-config --version foo.pc' rather 
than checkVersion. Still, I don't know where this check is best performed.

My motivation for this is to require PETSc >= 3 so the that PETsc 
wrappers can cleaned up.
