I'm perplexed. The only time I've run into this problem was when I forgot
to link with libcrypt. Deja didn't turn up anything useful, either.

I hate to point out the obvious, but, by default the Linux section in
Setup.in reads:

  #
  # Use this on Linux.
  #
  #gvibBase gvibBase.c -D$(GVDEF) -I$(PYDIR) -L$(IBLIB)  -lgds -lcrypt

Note the comment. You need to comment the Solaris line, and uncomment the
Linux line. In reality, the link with libcrypt is the only thing
differentiating the two.

Unfortunately, the compile will still succeed without -lcrypt being 
specified. You won't see the problem until you try to import the module,
as seen above.

One other thought. The first time you run:

  make -f Makefile.pre.in boot

a Setup file is created. If you then change Setup.in, you need to delete
Setup and re-execute the above line. Otherwise, the changes won't be
reflected.

I'm sure it's something simple. Stay in touch with Bob and I; we'll help
you get it working.
