Yes - some code compiled for compute nodes also run on the frontend -
but not all..

Nope.. I get:

Cannot run executables created with FC. If this machine uses a batch system 
to submit jobs you will need to configure using/configure.py with the additional option  --with-batch.
 Otherwise there is problem with the compilers. Can you compile and run code with your C/C++ (and maybe Fortran) compilers?

I have tested with sizeof.c [in src/benchmarks] and this code compiles
fine with mpicc - and runs on the front-end. I guess I need to find a
trigger that stops this from working..

login1.surveyor:~/junk > mpicc sizeof.c

double      : 8
