After a fresh install of Haskell, and following the instructions above, I end up with the following rather bizarre and unexpected problem:
$ cabal install git-annex --bindir=$HOME/bin -f\"-assistant -webapp -webdav -pairing -xmpp -dns\"
Resolving dependencies...
Configuring pcre-light-0.4...
Building pcre-light-0.4...

Failed to install pcre-light-0.4
cabal: Error: some packages failed to install:
git-annex-3.20120230 depends on pcre-light-0.4 which failed to install.
pcre-light-0.4 failed during the building phase. The exception was:
ExitFailure 1
This is a somewhat older Mac OS X 10.6.8 system.
I do have PCRE already installed via Fink, and pcre.h is in /sw/include. I see other -I/sw/... things in the compile command above, but obviously /sw/include is not one of them.
Any clues for me?
(Why the heck does git-annex need pcre in particular anyway??? I saw another regex library get installed earlier somewhere in this (massive) process.)
