Shu-thing.hs:4:27:
Module
`Control.Exception'
does not export
`Exception(ExitException)'
cabal: Error: some packages failed to install:
Shu-thing-1.1.1 failed during the building phase. The
exception was:
ExitFailure 1
What version of ghc and cabal are you using? shu-thing builds on
ghc-6.8 and failed on ghc-7.*. Package probably broken and need to
be updated, due to changes in other packages.
The other package that changed is base; it's still using old-style exceptions. I thought someone was going to package up old-exceptions and put it on hackage for backward compatibility, but I don't see it there. Same with the other package they tried to install.
