install yesod on FreeBSD

This is for FreeBSD 10.0

$ sudo pkg install hs-haskell-platform
$ cabal update

... now this says that we should upgrade with: cabal install cabal-install
... but do NOT do it, otherwise some packages will not find some header files

$ cabal install yesod-platform yesod-bin --max-backjumps=-1 --reorder-goals

... this takes long

$ ghc-pkg list | grep yesod
    yesod-1.2.5.2
    yesod-auth-1.3.0.4
    yesod-auth-hashdb-1.3.0.1
    yesod-core-1.2.14
    yesod-form-1.3.8.2
    yesod-persistent-1.2.2.3

    yesod-routes-1.2.0.6
    yesod-static-1.2.2.5

If you happen to mess up the ghc/cabal packages, just

rm -rf ~/.cabal ~/.ghc/
