A test installer for a patched version of ghc-6.4.1 for Windows is now available, http://haskell.org/ghc/dist/6.4.1/ghc-6-4-1-bld1.msi Unless I'll hear of any packaging snafus, it'll be hooked up to the GHC web pages tomorrow. Notice that by default this installer will deposit bits in the same directory as the original 6.4.1 installer, so if you treasure the original bits.... The installer includes all 6.4.1 fixes committed as of 2005-10-20T01:00:00+0000. In particular, usage of Cabal from a GHCi-like setting should now work OK. --sigbjorn
