Embarassing - I simply forgot to include Fib.o in the link.
So it links now (program crashes, but I can try to sort that out).
I'm still intereted in knowing how to automatically get the list of
required libraries.

The only other way I can think of is to construct the arguments yourself by
querying the package database, e.g. "ghc-pkg field ld-options rts", but
you'll have to combine the information from several different fields of the
packages you use, and basically reproduce what GHC does to construct the ld
command line.
