[dcmf] running my own mpich

[Robert Latham]

I've made some changes to ROMIO and would like to test them out.  I've
built an mpich library with the the 'make mpich' rule, and that goes
just fine: i've got an install/bin/mpicc which links in
install/lib/libdcmfcoll.cnk.a install/lib/libdcmf.cnk.a and
install/lib/libmpich.cnk.a

So far, everything looks normal.

When I try to run the resulting program, I get a segfault.  Here's the
output after running the stack dump in one of the lightweight core
file through addr2line:

If I had to guess, I'd say that the libdcmf in the development tree is
incompatible with argonne's V1R1M2_500_2007-071213P driver.  What's
the best way to test out my ROMIO changes?

Thanks
