That's *WEIRD*. It's as if you have the old base from GHC 6.8. Is cabal-install doing something (weird|evil|smart) here? That code is in this block: #if __GLASGOW_HASKELL__ >= 610 ... instance Exception SqlError where ... #endif And it acts as if you're compiling against GHC 6.8!
I got that error when using cabal to install. However, when I downloaded the package and installed it with a ./Setup.lhs configure..., it worked. Maybe this is a cabal issue instead.
Leads me to think even more that there's cabal-install trickery here. Can someone enlighten us on that? Is cabal-install playing tricks with base? -- John
