[mpich-discuss] Re: Getting MPICH2 to find/use g95 fortran

[Pavan Balaji]

It looks like configure failed. Can you send the complete configure 
output? If you are using bash, you can do:

   $ ./configure --prefix=/usr/local/mpich2/mpich2-install 2>&1 | tee 
configure.log

   $ make 2>&1 | tee make.log

   $ make install 2>&1 | tee make_install.log

If you are using a different shell, you can refer to the README in the 
top-level directory.
