[ 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 }

GHC 7.4.2是否与OS X Haskell Platform一起安装？ –
是的，我用自制软件安装了haskell平台 – Heptic
