What on earth are you doing that mixes Haskell, C++, Scala, and Python?
I am very intrigued by the very idea of such a project. :-)
I have to confess that don't care for waf myself because I had
unpleasant experiences using it which stemmed in part from its design
which I also didn't like. For example, if you don't get the proper
complex incantations correct then it will simply fail silently without
giving you any hint as to what you might have gotten wrong, even for the
most basic of tasks! Also, the last time I looked into waf in depth a
couple of years ago the basic task model was designed around a language
like C++ where there is a build phase and then a link phase and
everything within a phase can be built in any order, so to compile
something like Haskell code you need to essentially put every file in
its own phase, but the scheduler they used for phases was not optimized
at all precisely because they were assuming a C++-like model where there
were only a couple of phases; they could have changed this since then,
though.
But anyway, I am always willing to keep an open mind about tools if
someone convinces me that my current negative impressions about them is
wrong or outdated, so if you got waf to build a project with all four of
those languages then that does definitely give it extra points in my
book. :-)
Cheers,
Greg

Waf supports parallel builds and works with GHC without too much
trouble. I use it in a mixed Haskell, C++, Scala and Python build. If
there is interest I could conceivably clean up the ghc waf tool and
release it.

While I do appreciate you stepping in to defend autotools (if for
no other reason then because someone has to so that the discussion
is balanced :-) ), I think that you are wrong to say that
autotools is unusual in getting the idea of parallel builds right,
since in my experience the opposite is the case: most systems
support parallel builds --- such as SCons, CMake, I think waf,
etc. --- with Cabal being an outlier here.
