With a specific package (bindings-common, with the latest version in hackage) if I ask GHCi to read it I get:

ghc-6.8.2: /home/mauricio/lib/bindings-common-0.2.5/ghc-6.8.2/HSbindings-common-0.2.5.o: unknown symbol `atexit'

If I build a library or executable cabal package depending on it, I have no problems. Also, if I remove that 'atexit' wrap from 'bindings-common' I don't get this ghci error message anymore.

This is actually not specific to that package. Attached is a darcs patch to a package where the only exported module contains just a wrapped 'atexit'.
