You're welcome

I know: this is in CPMD distribution.
The question is: what is exactly mpif77 ?
It is a wrapper, i.e. it calls xlf with some flags that do not appear  
here,
but are defined during MPI installation.
Can you give us the result of the following command:

mpif77 -show

This will show what are the "hidden" flags.
For example for me, it yields:

/opt/ibmcmp/xlf/8.1/bin/xlf_r -L/opt/mpich-mx/lib -lpmpich -lmpich - 
lpmpich -lmpich -L/opt/mx/lib -lmyriexpress -lSystemStubs

which means that FC FLAGS are overall:
-L/opt/mpich-mx/lib -lpmpich -lmpich -lpmpich -lmpich -L/opt/mx/lib - 
lmyriexpress -lSystemStubs AND -c -g -C

What version of Mac OS X do you have ?
10.3.9 or 10.4.x ? Could you type gcc -v (this will provide us info  
about libs installed)
The -lSystemStubs is 10.4 specific

Fine

Could you ask the administrator for the configure (or even better,  
the config.log)  command used for MPICH ?

Weird, but ok...
