Thanks for the reply.
Otherwise, you'll need to go digging in your library for the .o files to link to by hand.
If I look with '-v' tho it seems to include Haskell libs in the underlying link - see below? Plus it only complains about this library, I use many other standard libs too? Looks like something stranger is going on? Also I've tried using --include-pkg-deps (perhaps incorrectly) - it doesn't help.

Sorry, I missed that you'd tried that. Why would you not want to use --make? The issue is that when you import a module in your standard library, you need to link to it, and ghc --make takes care of figuring
