[Haskell-beginners] Disappearing Module Problem

[Michael Craig]

I'm trying to install aeson and http-enumerator on an otherwise fresh
installation of ghc 7.2 on OS X 10.7. I was inspired by beastaugh's gist on
getting cabal-install running on Lion: https://gist.github.com/1169332.

I can install either aeson or http-enumerator and it'll work fine. However,
as soon as I install the second one the first one disappears. The files are
all there in .cabal/lib, but ghc can't find the module.

Any ideas?
