Okay, that works.  Easy first check.

Make sure you linked with the right libraries:

    ldd $(which qstat)
    ldd ./mpiexec

Then try torque debugging:

    PBSDEBUG=yup ./mpiexec -n 1 hello

Then try the big hammer:

    strace -vFf -s 200 -o /tmp/mp-st.out ./mpiexec -n 1 hello

And see if you find anything suspicious in there.

If you happen to know your server name, you should be able to do:

    PBS_DEFAULT=cromo.ufabc.edu.br ./mpiexec -n 1 hello

But I'm still guessing that your server default file is missing.
Look in the strace for paths it opens.  The one ending in
"/server_name" is what you want to investigate.
