[Haskell-cafe] unable to load package `regex-posix-0.94.2' (On Vista x64)

[Stephen Tetley]

Maybe you want to hide the old version of regex-posix:

> ghc-pkg hide regex-posix-0.94.2

http://www.haskell.org/ghc/docs/7.0.1/html/users_guide/packages.html

Note - I don't use cabal install myself so this might not be the right
way to do things, however "ghc-pkg hide ..." is reversible with
"ghc-pkg expose ..." so I can't see it doing any harm.
