setting the default package path

Hi all, I'm quite new to Haskell and GHC, please accept my apologies if I have missed something obvious in the FAQ/Documentation... On Windows, using the binary distribution of GHC Cabal packages are, by default, placed into C:\Program FIles\Haskell - if the --prefix option is not used when configuring the package in order to indicate some other location. Can I change this default location? Thanks, Lars -- Lars Oppermann Hamburg, Germany
