Yes, this started working until:

Resolving dependencies... 'unix-compat-0.1.2.1' is cached. Configuring unix-compat-0.1.2.1... exactly Preprocessing library unix-compat-0.1.2.1... Building unix-compat-0.1.2.1...

System/PosixCompat/Files.hsc:83:7: Could not find module `System.Time': it is a member of package old-time-1.0.0.0, which is hidden cabal: Error: some packages failed to install: unix-compat-0.1.2.1 failed during the building phase. The exception was: exit: ExitFailure 1

I don't understand this: unix-compat depends on old-time (if I trust http://hackage.haskell.org/cgi-bin/hackage-scripts/package/unix-compat-0.1.2...), so this should be made visible by cabal.

There might be an issue with pre-processing, but that's beyond my cabal knowledge.

Maybe some cc'ed wizards can help :)

I cannot reproduce that failure, it just works for me. What versions does "cabal --version" report? And using ghc-6.8.2? Duncan
