Done! Checked it into MPICH2 cvs yesterday (took me a while to find
this mail)

It's installed with execute set.  Does it need to be +x in the tree
too?

Totally agree.  I'm quite happy to have ROMIO using pvfs2-config.
Thanks for the kick in the pants to get that working at last.

The mechanism I used to feed libraries up to MPICH2 is, well, MPICH2
specific. The old approach of setting CFLAGS/LDFLAGS/LIBS will still
work, so we're still backwards compatible and compatible with other
MPI implementations.
