The first patch breaks “ghc-easyplot”.

I’m currently building some packages to test the other patches, and if
everything builds fine, they LGTM with some minor tweaks (which I’ve
already made).  Should I push it to master or staging?  It means
rebuilding all of our Haskell packages, which is a few hundered
packages.

Robert, do you know why the first patch doesn’t work?  Should I just
omit it?
