My guess is that it was compiling fine, just very slowly.  C++ is slow
everywhere, but usually not this slow.  What sort of file system do you
have?  Is it really slow?

You can compile Elemental separately and tell PETSc to use it.  The
timeout can also be increased, but PETSc/BuildSystem should implement a
better solution.

Finally, a friendly reminder to upgrade to petsc-3.5.
