I don't know for sure if it is a bug in haste or in ghc/ghc-pkg (maybe ghc-pkg should reject such packages from being installed at all, since ghc chokes on them anyway?). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11050#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
