Yes, this is a bug -- it should be LDFLAGS instead of LSFLAGS. I'll
fix that today and get it pushed out into our release branches so
that both 1.0.3 and 1.1 will contain the fix.

We go back and forth on this one, actually. We don't want Open MPI
to fail to configure if there is no I/O component available, in part
because developer testing builds generally don't want to wait for
ROMIO to build.

However, we really *should* abort configure and warn the user if --
enable-io-romio is given and ROMIO fails to configure. I will fix
this with the LDFLAGS fix. I'll let you know when the fixes become
