Re: [Haskell-cafe] zlib, missing zlib.h
You need to install the C zlib library. Cabal is currently unable to warn about missing C library dependencies, but they manifest as undeclared identifiers in .hsc files when that's the case. -- Don tphyahoo: Tried to install http://hackage.haskell.org/cgi-bin/hackage-scripts/package/zlib which is required for http://darcs.haskell.org/cabal-branches/cabal-1.4 which is required for cabal-install.

Try patching the cabal file using something like that.

Actually the .cabal file is fine, the machine is probably just missing
zlib.h which is in zlib-devel on debian based systems.
As don says, Cabal does not currently check that all required .h files
and C libs are available at configure time so you bump into them as
compile or linker errors. Obviously it should check for these things at
configure time and produce more helpful explanations. If anyone wants to
implement that for us that'd be a great service. The ticket is here:
