I am getting the following error :-

    C:\Languages\Lexer\Haskell>cabal install ranges

    Resolving dependencies...

    cabal: Error: some packages failed to install:

    ranges-0.2.3 failed while unpacking the package. The exception was:

    user error (TAR checksum error)

I am on Windows Vista, is it possible to clean or delete Cabal's cache ?

Many thanks in advance,

Aaron
