Neil ran into these symptoms:
Cabal documents itself as having a --builddir command to
change the placement of dist stuff, which is fantastic.
However, running with GHC 6.8.3, Cabal 220.127.116.11, I get:
cabal build --builddir=../../../_make/Tools/ext/haddock-0.9/dist
setup.exe: Unrecognised flags:
i.e. cabal accepts the --builddir command, but the setup
that cabal builds doesn't. Why?
Two things are needed to fix this, one is a proper checked specification of the command line interface so that cabal-install always knows what flags the Setup supports. The other is to track the version of the Cabal lib used to build the Setup and to recompile it if that changes.
Note that this should happen automagically if we use a proper dependency tracking framework. In the mean time it'd require keeping an extra state file in dist/setup.
