I'm not quite sure what has gone wrong here. GHC is reporting a clash
between the module Generics in the lang package, and the local module
Generics.
The lang package is not supposed to be in scope, however. Looking at
the command line, the only package flag is '-package Cabal'. Does your
Cabal package somehow depend on lang? (it shouldn't -
Cabal/package.conf.in specifies a dependency only on base).
Ah - do you have a local Cabal installation, perhaps?
Cheers,
Simon
