It looks like you did not install mpiexec on all the nodes in the cluster;
perhaps you only installed it on the head node? If so, this would explain
why it's not found when you try to run it in a PBS job -- the job itself
will run on one of the nodes, and therefore it must be able to find
/usr/local/bin/mpiexec there.
Also, you shouldn't need to provide the whole directory to mpicc; if you
use switcher properly, it should be in your path automatically. For
example:
shell$ switcher mpi = mpich
Then for all future shells, the MPICH stuff should be in your path.
