In reply to my own email, I have worked around the problem by 
downloading f2cl and running it by hand to translate the three
Fortran routines I needed.  I have a working implemetations
but need to test and document.

I still don't understand:
 - how to define the necessary logical pathnames required by slatec.system
   (I googled some documentation and examples,and worked through them, but
    just ended up more confused)
 - how to drive the slatec.system file
This would be useful information to have somewhere.
