Hm - there is no error message [or error number] listed.

Perhaps you can try debugging this without PETSc. i.e compile/run a
simple code and see if it works.

You can use src/benchmarks/sizeof.c or
http://trac.mpich.org/projects/mpich/export/60482cc2ca9a740d049444a9261a04a3007bc306/examples/cpi.c

[perhaps runs from $HOME work - but not /tmp ? - but then you said -
'This workflow seemed to work for pgi & gnu programming envs' - so
this shouldn't be the problem]
