According to a report from Adam Moody, there is a compile error with

ROMIO and Lustre 2.4.0.  It has been solved upstream already; here's
the ticket:

    http://trac.mpich.org/projects/mpich/ticket/1973

And here's the commit that fixed it:

    a0c4278f14

OMPI does not have the other code referred to in that git commit (in
ad_lustre_hints.c).

Thanks to Adam Moody for reporting the issue.
