[darcs-users] build failure on Debian

[Dave Love]

I can't build the current screened or reviewed repos on Debian stable
(haskell-platform-2012.2.0.0) as I used to be able to.  After cabal
update I get:

  $ cabal install
  Resolving dependencies...
  cabal: Could not resolve dependencies:
  trying: darcs-2.9.7 (user goal)
  trying: darcs-2.9.7:-use-local-data-map-strict

  template-haskell==2.7.0.0/installed-8c8...)

Is Debian stable just not supported now (which I think would be
unfortunate)?
