How/where are you hitting it?

Cabal is shipped as part of ghc: ie it is a core library -
needed for ghc-pkg, etc..  (hugs98 is now old and unmaintained/inactive.)

$ rpm -ql ghc | grep Extension.hi
/usr/lib64/ghc-6.12.1/Cabal-1.8.0.2/Language/Haskell/Extension.hi

I think it should be in Cabal-1.8.0.6 in ghc-6.12.3.

Hope that helps, Jens
