[MPICH] mpif90 issues

[Mike Zupan]

I am thinking this might be a pgi 6.0 error?? I just used mpich2 on both a 
32bit machine and 64bit machine and got this again

[wind at fcst3 mpich2-1.0.2p1]$ ./bin/mpif90 
/usr/local/pgi-6.0/linux86/6.0/lib/f90main.o(.text+0x77): In function 
`main':
: undefined reference to `MAIN_'


I am just setting these enviroment vars

export F90="pgf90" 
export FC="pgf77" 
export F77="pgf77"

we don't have the license for the C pgi compiler
