Although Haskell is an essential part for Quickcheck in Isabelle and it 
would simplify the installation process for Quickcheck, I am not in 
favour to provide ghc contributed with the Isabelle distribution.
So GHC must be installed by the usual means of the operating system, 
e.g., through some package manager.
Providing GHC as a component might try to help to install GHC on the 
operating system, or could try to detect the path of GHC automagically, 
but I do not have a clear vision how this should work.
