Yeah, that's one of the major differences between using an interpreter
like Hugs or ruby and a compiler. (GHC does offer a --make option that
chases down dependencies for you.)

I haven't used NHC so I can't guarantee this will work, but try doing
something like this:
$ nhc98 -c RC4.hs
$ nhc98 -c prng.hs
$ nhc98 RC4.o prng.o -o prng
The first two steps will create (unlinked) object files, and the third
step should link them together into an executable file "prng".
