$ cabal --version cabal-install version 0.6.2 using version 1.6.0.1 of the Cabal library
$ ghc --version The Glorious Glasgow Haskell Compilation System, version 6.11.20090724
$ cabal install zlib Resolving dependencies... Configuring zlib-0.5.2.0... ghc-stage2: /home/alatter/.ghc/x86_64-linux-6.11.20090724/package.conf:6:163: parse error on input `Nothing' cabal: Error: some packages failed to install: zlib-0.5.2.0 failed during the configure step. The exception was: exit: ExitFailure 1 <<<
I finally noticed that the error is coming from the new GHC executable, not the cabal-install executable. So building the new version won't help me, as evidenced by trying to run 'ghci' in this state:
$ ghci GHCi, version 6.11.20090724: http://www.haskell.org/ghc/ :? for help ghc-stage2: /home/alatter/usr/lib/ghc-6.11.20090724/package.conf:40:168: parse error on input `Nothing' <<<
It looks like I'm not allowed to install any GPL or LGPL licensed software with Cabal :-) Antoine
