It helps to understand that they are made by different people and
cabal-dev is "just" a wrapper around cabal. Out of curiosity I just
tried 'cabal-dev install -j' and as far as I can tell right now it
does support -j. Perhaps you need to install newer versions of cabal
or cabal-dev?

$ cabal-dev --version
cabal-dev 0.9.1
built with Cabal 1.16.0
