I agree that this is an oversight. I will put it in the development version,
and it
will appear in the next release.

Also, can you tell me if there is there any likelihood in the near future

This is more problematic. Most F90 compilers have an array descriptor that
is a
variant of the NAG format. However PGF90 does not, and these refuse to tell
us the layout. Thus we cannot add those routines.

   Thanks,
