[Haskell-cafe] Problem with cabal install zlib

[Max Cantor]

I actually ran into this problem last night.  Here's my workaround (note that it involves downgrading to zlib-0.5.0.0

1) unregister the zlib-0.5.2.0 package (prompt> ghc-pkg unregister zlib-0.5.2.0)
2) rebuild and install cabal-install:
	prompt> tar -zxvf ~/.cabal/packages/hackage.haskell.org/cabal-install/0.6.4/cabal-install-0.6.4.tar.gz
	prompt> cd cabal-install-0.6.4
	prompt> runghc Setup.hs configure --user && runghc Setup.hs build && runghc Setup.hs install

Note that this requires that you still have zlib-0.5.0.0 installed.  Also your paths and options for configuring may vary.  But, this worked for me.
