Maybe it is a missing dependency to dev-haskell/base-prelude ?

Prelute should come from ghc's base. The culprit here is missing profiling libs of ghc itself. Can you post 'emerge --info ghc'? It's probably missing USE=profile on ghc (and missing dependency for libraries).

Sorry, I no longer have this setup, after Haskell go too annoying, I removed it completely.


But I vaguely remember setting:
"dev-haskell/* profile" in my packages.use

but not for dev-lang/ghc. So you might be right.
