Comment(by simonpj):
OK that helped. I had a similar error in `Static/AnalysisLibrary` which I
fixed with an error thunk thus:
{{{
let mt = error "urk"
-- mt <- if checkUri file then return noTime
-- else lift $ getModificationTime file
}}}
But then everything compiled. No overlapping instance error. Now what?
