I think you installed zlib without proper flags to link with 32-bit libraries. configuring with ./Setup configure --with-hsc2hs='--cc-flag=-m32 --ld-flag=-m32' should do the tricks.

The following worked like a charm:

cabal install --hsc2hs-options='--cc-flag=-m32 --ld-flag=-m32'

Which version of 6.12 are you running? These options or manually patching the hsc2hs wrapper should not be necessary with 6.12 anymore. (They are only a temporary workaround to use the old 6.10 release on Snow Leopard.) Manuel
