Ok, I've finally sorted it!
This had me completely stumped for ages. then. I was confused because Homebrew
was denying anything to do with cabal-install:
% brew uninstall cabal-install
Error: No such keg: /usr/local/Cellar/cabal-install
I flailed around a bit, and tried replacing the Haskell Platform binary with
one from Homebrew. Then I discovered I had GHC installed via Homebrew. I didn't
think it was a problem, then I realised what my PATH was set to:
PATH=$HOME/Library/Haskell/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
So zsh was getting cabal from $HOME/Library/Haskell/bin, but then finding ghc
in /usr/local/bin (Homebrew) before /usr/bin (Haskell Platform). I have no idea
what combinations of libraries it was using.
I have no idea if recompiling ghc from inside Homebrew would have helped, or
uninstalling ghc and using Homebrew's haskell-platform package (or recipe, or
whatever they're called).
Thanks for your help. I'd really love to be able to help with the Mac
continuous integration problem, unfortunately, I just can't spare the time to
figure out these sorts of things when I get stuck. (You could argue that since
this time I *did* spare the time, I just disproved my point. Stubbornness got
the better of me.) There must surely be an simpler yet reliable way for
non-Haskell-developers to install darcs on a Mac though.
Anyway, I now have darcs 2.8.4 installed, and that's the main thing :-D
Thanks
Ash
