It's possible libmesh is using the wrong mpicc/mpicxx compilers when
you use this configuration line.  It will use the first one it finds
in your path, *not* the one you downloaded with PETSc.

So could you try:

CXX=/path/to/petsc/mpich/bin/mpicxx CC=/path/to/petsc/mpich/bin/mpicc
./configure

and see if you have any better luck with the executables?
