GHC 7.6.1 ships with a buggy Cabal
Using ghc 7.6.1
$ rm -rf ~/.cabal # To force a new default config being written $ cabal update # To write default config Config file path source is default config file. Config file /home/bardur/.cabal/config not found. Writing default configuration to /home/bardur/.cabal/config Downloading the latest package list from hackage.haskell.org $ cabal install foo cabal: Command.optionToFieldDescr: feature not implemented

Although this particular bug doesn't seem to be severe since once you remove the incorrect jobs line in the .cabal/config file it starts working again, it is quite annoying.
