Error while installing new packages with GHC 7.4.1

[Antoras]

Ok, I got Hoogle to work with GHC 7.0.3. I abandoned my try to update to 
the newest version of GHC, due to some other things which don't work. 
For example I can't import Data.Map any more.

As long as these errors occur I see no reason to switch to a newer version.

With Hoogle 4.2.9 I could successfully create a database and work with it.

Neil, thanks for your update, once again.
