Hi,

I wanted to use LLVM as backend for GHC and all my Haskell packages. When I do
this, hs-cabal-install is unusable. Simple commands like "cabal update" or
"cabal build" crash with segfaults. Removing the option LLVM for all the
packages in Haskell's environment makes hs-cabal-install usable again.

Option LLVM does not affect all Haskell packages. It is only a problem with
cabal, which I've identified so far.

Hint:
To change options, you need to erase all previous settings in /var/db/ports
which affect lang/ghc and */hs-*, then rebuild all packages.
