Hmm... did you request PETSc to download/build its own MPI? And only static
libs?

Just wondering because it looks like your MPI and PETSc
/home/ubuntu/Dev/petsc/arch-linux2-c-debug/lib/libmpi.a
/home/ubuntu/Dev/petsc/arch-linux2-c-debug/lib/libpetsc.a

are both static (foo.a) libs. If this was intentional, you'll probably need
to configure libmesh with --disable-shared --enable-static (yes, you need
both) to be consistent with PETSc and MPI.
