Ummm..., so how do I build the version of Haddock included in the GHC 
source tree under utils? I tried just

$ cd utils/haddock
$ make

but that fails with

===--- building final phase
make -r --no-print-directory -f ghc.mk phase=final all_utils/haddock
make[2]: *** No rule to make target `all_utils/haddock'.  Stop.
make[1]: *** [all_utils/haddock] Error 2
