this is an unrelated error that has no consequences. There should be  
another error
that causes "configure" not to recognize the parallel environment.  
Anyway: if mpif90
uses gfortran, it will not compile properly QE unless it is a recent  
version. It doesn't
seem to be your case. If you cannot modify the software on the  
machine, the only
thing you may try is to install on a private directory a working  
compiler (e.g. intel)
and a mpi wrapper for it. Not sure it will work, though, in your case.
