Hi Eileen

Just a guess.

You seem to be building mpich on an NFS shared directory (/net/...).
The local machine and the NFS server clocks seem to be out of sync.
'make' will get confused with this.

These warnings suggest it:

*******************************************************
make[2]: Warning: File `src/binding/f90/mpi_constants.lo' has 
modification time 1.1e+02 s in the future
   FCLD     lib/libmpichf90.la
   CC       src/env/mpichversion.o
   CCLD     src/env/mpichversion
make[2]: warning:  Clock skew detected.  Your build may be incomplete.
make[2]: Leaving directory 
`/net/server/opt_local/MPI/mpich-3.0.4/mpich-3.0.4'
Making all in examples
*******************************************************

I would first synchronize the two machine clocks (use ntp !),
or as an easier alternative, build mpich on a local directory,
starting fresh in both cases.

My two cents,
