无法在 Mac OSX 上安装 scion 浏览器

Question

cabal install scion-browser给出：

[ 6 of 23] Compiling Scion.PersistentBrowser.Query ( src/Scion/PersistentBrowser/Query.hs, dist/build/scion-browser/scion-browser-tmp/Scion/PersistentBrowser/Query.o )
src/Scion/PersistentBrowser/Query.hs:258:58:
    No instance for (MonadResource IO)
      arising from a use of `get'
    Possible fix: add an instance declaration for (MonadResource IO)
    In a stmt of a 'do' block: Just dc <- get declId
    In the expression:
      do { Just dc <- get declId;
           getDbModule dc }
    In an equation for `getDbModule':
        getDbModule (DbConstructor _ _ declId)
          = do { Just dc <- get declId;
                 getDbModule dc }

和其他一些信息：

这是一个已知问题，请参阅 https://github.com/JPMoresmau/scion-class-browser/issues/4。将在下一个版本中修复（也许我将在2012年12月15日左右发布本周）
