I am struggling with running make on MPICH, V3.1. I believe that ./configure went well but I do not understand what caused the errors in make. I thought it may be associated with the fortran compile but I have F77 installed (though somewhat confused whether fortran 90 is also installed). The README file suggested that I send an email to this list with nominated four text files attached. The end of the m.txt file is included here for easy access, full details are attached...
