Comment (by MikolajKonarski):

 To work around zlib problems I had to add hsc2hs options:
 {{{
 cabal install zlib --ghc-option="-optc-m32" --ghc-option="-opta-m32"
 --ghc-option="-optl-m32" --ld-option="-melf_i386" --hsc2hs-options="--
 cflag=-m32 --lflag=-m32"
 }}}
 This was inspired by
 {{{
 http://www.haskell.org/pipermail/glasgow-haskell-
 users/2009-November/018070.html
 }}}
 and was needed despite
 {{{
 https://ghc.haskell.org/trac/ghc/ticket/3400#comment:16
 }}}

 Now everything works correctly for me. Next up for testing would be a TH
 heavy package or just a very large application. Yesod comes to mind.
 Please report here if you try that.
