[Haskell-cafe] Package Management with Stack?

[Jun Inoue]

Thanks for the suggestion, Adam.  That does it for xmonad-contrib.
Unfortunately, it fails when I go on to add xmonad-extras, probably
because the version of xmonad already installed can't be resolved with
the available version(s) of xmonad-extras.  (I forgot to note exactly
which packages I had before, so I'm installing these things one by
one, based on compilation errors of ~/.xmonad/xmonad.hs.)

  $ stack install xmonad-extras hint-0.6.0 libmpd-0.9.0.6 --resolver lts-8.4

  Error: While constructing the build plan, the following exceptions
were encountered:

  In the dependencies for xmonad-extras-0.12.1:
      hint-0.6.0 must match >=0.3.3.3 && <0.5 (latest applicable is 0.4.3)
      libmpd-0.9.0.6 must match >=0.8 && <0.9 (latest applicable is 0.8.0.5)
      xmonad-0.13 must match >=0.10 && <0.13 (latest applicable is 0.12)
      xmonad-contrib must match >=0.10 && <0.13, but the stack
configuration has no specified version
                     (latest applicable is 0.12)

  Recommended action: try adding the following to your extra-deps in
/home/jun/.stack/global-project/stack.yaml:
  - xmonad-contrib-0.12

  You may also want to try the 'stack solver' command
  Plan construction failed.

Adding the fact that I seem to have to list a lot of deps on the
command line or in stack.yaml and Brandon's suggestion that I'm using
this tool for the wrong purpose, this seems like a deal breaker for me
:(
