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

[PattiMichelle]

Pavan:

Thank you very much for offering to look at the output of my install... 
I had a look in the configure.in file and saw references to g95, so I
assume it will be looking for it.   Please find the logfiles (with
slightly different names) attached and let me know if you are unable to
receive them!

Thank You,
Patti
