Strange things are indeed afoot in the package system. Mostly they are explainable, but the diagnostics are really terrible right now (I've improved this to some extent in the current sources). > To reproduce: > > * Install hs-plugins and download yi+gtk.

Yes, it will have been hidden when you installed the new Cabal, to avoid conflicts. ghc-pkg does tell you about this, if you watch the messages carefully. > $ ghc-pkg expose plugins-0.9.10 > > Try again: > $ runhaskell Setup.lhs build > Preprocessing library yi-0.2... > Preprocessing executables for yi-0.2... > Building yi-0.2... > ghc-6.5: ghc-6.5: panic!

Yes, because Cabal-1.0 is now found again. ghc-pkg should probably warn/complain that unregistering Cabal-1.0 is a bad idea. The dependency of plugins on Cabal causes other problems when you have two versions of Cabal installed. What you should really do is upgrade Cabal first, *then* build and install hs-plugins, then build yi.
