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:

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.
