Reported by Nicolas Martyanoff <khaelin@gmail.com> on glasgow-haskell-users. I expect the build system is picking up Cabal 1.9.0 in preference to the version in the source tree.

I thought it might be good to build GHC 6.12.1 with itself just to be sure it's working fine before make a dist, but I now get the following error:

gmake: *** [all] Error 2

I tried to "ghc-pkg mask" Cabal-1.8.0.2, then Cabal-1.9.0, didn't change anything.

Does someone know what's going on here, and what can be done to fix it ?
