Many errors of this type can be avoided by using cabal-dev [1] instead
of cabal-install for development -- cabal-dev keeps package databases
for each project separate, although everything still also uses the
global package db (so you shouldn't install anything there).
cabal-install is still necessary (and ideal) for installing
applications for use in normal activities, and for installing
libraries into your user-package database for use in general ghci
sessions.

If nothing else, cabal-dev will ignore your user package db, which
might be enough to get you going on whatever you're really doing
instead of fixing your user package db right this moment :)
