Yeah, some minor trickery is required. I believe you can just do
something like:

  ./configure <options> --with-file-system=panfs+nfs+ufs

but it's probably safest to do:

  ./configure <options> --with-io-romio-flags="--with-file-system=panfs
+nfs+ufs"

Changing the filesystems you want to include, of course.
