Try

    --with-pbs=/usr/local/torque

(or wherever you installed the built torque) instead of --with-pbssrc.
Without that option it picks up -lpbs from some standard system
location, perhaps /usr/local/lib.

Oops.  Here's a patch for that and the socklen_t warnings.  Every
compiler always finds more bugs it seems.

It's actually okay to use gcc here even though your MPI codes are
compiled with something else.  mpiexec itself is not an MPI application
so it won't even look at your MPICH library.
