Weird, I get a:

$ cabal bench
cabal: unrecognised command: bench (try --help)

and I'm running the latest cabal-install from HEAD:

$ cabal --version
cabal-install version 0.11.3
using version 1.11.3 of the Cabal library

Weird indeed. If you use Setup.hs directly it work:

$ ghc -O Setup.hs -fforce-recomp -package-conf ~/src/cabal/Cabal/dist/package.conf.inplace
