You are right! Something in the current Makefile causes interpsys
to be re-built even though the only thing that has changed is
the *.NRLIB's. I noticed this but it did not occur to me that
re-building interpsys would have any effect. I thought that this
was just an inefficiency in the Makefile dependencies.

I will look more closely at the Makefile to see if I can tell
why interpsys is being rebuilt.

I wonder if both are necessary or is it only the change in
