我试图在我的FreeBSD盒子上整天安装Happstack。 最后我安装了GHC 6.10.x. 和Cabal 0.8.2。 但是在Happstack上失败了。 这些是错误的。
%sudo ~/.cabal/bin/cabal install happstack Resolving dependencies... cabal: cannot configure unix-2.4.1.0. It requires base >=4.2 && <4.4 For the dependency on base >=4.2 && <4.4 there are these packages: base-4.2.0.0, base-4.2.0.1, base-4.2.0.2 and base-4.3.0.0. However none of them are available. base-4.2.0.0 was excluded because of the top level dependency base -any base-4.2.0.1 was excluded because of the top level dependency base -any base-4.2.0.2 was excluded because of the top level dependency base -any base-4.3.0.0 was excluded because of the top level dependency base -any %sudo ~/.cabal/bin/cabal install base Resolving dependencies... cabal: internal error: impossible %sudo ~/.cabal/bin/cabal install base-4.3.0.0 Resolving dependencies... cabal: cannot configure base-4.3.0.0.

Perhaps you need to run 'cabal update' first? % 在所有这些程序之前，我做了cabal update 。 有什么问题？
您需要安装最新版本GHC（6.12。*）。 使用这个tarballs 。
