It would be nice if instead of --with-file-system=pvfs2, there were a 
--with-pvfs2=<path>.

That way, we wouldn't have to set CFLAGS/LDFLAGS/LIBS before configure, 
_and_ we could tell mpich2 exactly what include paths, lib paths, and 
libs to use via pvfs2-config (which, btw, doesn't seem to have the 
execute flag set on it when it gets built).  Of course, mpich2 would 
still have to be reconfigured when somehow the link line for pvfs2 
changed, but that's true in any case.

I guess this is more of a mpich2 issue than pvfs2, but it seems like 
pushing in that direction is a cleaner solution, i.e. who knows what 
libs we might by linking with in the future, when the problem is just 
going to pop up all over again.
