Have you tried doing a 'runhaskell Setup.hs clean' first?  You should also
try unregistering the unix-2.3 package (ghc-pkg unregister unix-2.3.0.0).

The global package database should be somewhere like

/usr/lib/ghc-6.6.1/package.conf

on my system it is in /usr/local/lib/ghc-6.8.2/package.conf.

The local (user) package database is in something like
~/.ghc/i386-linux-version/package.conf.

It is part of the ghc source, in utils/ghc-pkg.
