 I have tried to build the source tarball on FreeBSD, but it always stops
 somewhere around the documentation bits with the following error message:

 {{{
 [..]
 make -C utils/haddock/doc html SPHINX_BUILD=/usr/local/bin/sphinx-build
 make: illegal option -- -
 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable]
         [-d flags] [-E variable] [-f makefile] [-I directory]
         [-j max_jobs] [-m directory] [-V variable]
         [variable=value] [target ...]
 utils/haddock/doc/ghc.mk:22: recipe for target 'html_utils/haddock/doc'
 failed
 gmake[1]: *** [html_utils/haddock/doc] Error 2
 Makefile:129: recipe for target 'all' failed
 gmake: *** [all] Error 2
 }}}

 That is probably because FreeBSD has GNU make(1) as {{{gmake}}}, it should
 be invoked with that name, that is, the value of the {{{$(MAKE)}}}
 variable is not respected at the recursive invocation of make(1).

 I have attached a patch for the {{{haddock}}} repository that fixes this
 problem.
