What version of Espresso are you using?
Many HPC machines are configured so as to disable execution of  
parallel programs from the command line (you have to run them through  
a batch queue). If I remember correctly, the "configure" in the  
stable version (2.1.2) will fail in this case. The "configure" in the  
most recent development version (accessible from anonymous CVS, see  
file "README.cvs") has a workaround for that.

If the problem is not solved this way, it is possible that your MPICH  
environment isn't configured properly. Does your mpif90 actually  
work? Please try compiling some simple program with it.

P.S. you need not be root to compile Espresso.
