 cabal install --global usually fails because of missing privileges.
 sudo cabal install --global is quite messy since every intermediate file
 is then owned by root, so other tasks that wouldn't need privileges at
 all, now requires them to handle those files.
 I propose to add the possibility to configure a command to use when
 running the equivalent of "runhaskell Setup install" on the package.
 So that the user can set it in ~/.cabal/config and it will always be used
 when install --global is run.
