The thing is that ghc-pkg check returns nothing.

Okay, I think that's a good sign, sort of. Does
$ ghc-pkg list Cabal
list one Cabal-1.8.0.6 in the global db and one in the user-db?
If so, unregister the one in the user-db
$ ghc-pkg unregister --user Cabal-1.8.0.6
If it complains that would break anything, post the message.

Ah.
/Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.3/package.conf.d
Cabal-1.8.0.6
/Users/lyndon/.ghc/i386-darwin-6.12.3/package.conf.d
Cabal-1.8.0.6
I've been making all my cabal-installs from my user account though.
Shouldn't I disable the global cabal?

I tried it, and it seems to have cleared up the error.
