[O-MPI users] mpif90 error: undefined reference to `mpi_reduce0dr8`

[Brent LEBACK]

I'm building rc4 with a soon-to-be released pgf90.  mpicc and mpif77 
both seem okay.  When I compile
with mpif90 I get:
: In function `MAIN_':
: undefined reference to `mpi_reduce0dr8_'
pgf90-Fatal-linker completed with exit code 1

Your problem or mine?  I see these type extensions for bcast and various 
sends and receives in libmpi_f90.a,
but nothing for mpi_reduce.  Where should I be looking?

This is on an opteron cluster, SLES 9.

Thanks.
