happy is a program. ghc-pkg doesn't know about it.

Install happy from
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/happy-1.17

Note that happy 1.17 needs Cabal-1.2 and 1.16 needs Cabal-1.1.6.

Alternatively, don't build the extralibs at the same time as ghc and
install just the ones you need individually later. They're all available
on hackage.
