 Trying to install a package with cabal-install and Cabal from ghc 7.10-rc2
 consistently gives this error message (`primitive` is just an example):
 {{{
 peter at montebre:~> cabal install primitive
 Resolving dependencies...
 Configuring primitive-0.5.4.0...
 cabal: Distribution/Client/Config.hs:(246,37)-(299,9): Missing field in
 record construction configProf
 }}}

 This is my package database:

 I updated only those packages (from their versions in Haskell Platform)
 that would not compile with 7.101-rc2.

 I am setting this to highest as this issue would be very annoying for
 everyone.
