Firstly, discussion about the development versions of GHC usually take
place on cvs-ghc at rather than here (to avoid confusion).

The CVS HEAD currently requires Happy 1.14, which hasn't been released
yet.  It is available in the source tree (fptools/happy), so to build
the CVS HEAD you currently also need to either:

 (a) check out fptools/happy and use --enable-src-tree-happy when 
     configuring GHC.

 (b) Build & install Happy separately from CVS
