I think you might need to add the path to your default .profile/.login/.cshrc/.whatever
(which I am assuming you're not doing - I really can't tell from "I tried to append the
/usr1/guest/bin/ directory to my UNIX path before starting an IDL session")

I *think* when you use SPAWN, the subsequent shell in which the SPAWN command argument is
executed is *not* the one you started IDL in and therefore has no knowledge of what you
may have explicitly defined. The same sort of thing happens in make files in Unix.
