[Haskell-cafe] Fwd: hackage compile failure with QuickCheck 2.5

[Levent Erkok]

Thanks Alexander. However, I'm not sure how to use the workaround described
so I can get hackage to properly compile my package. It sounds like I have
to add a "template-haskell >= 2.7.0.0"  dependency to my own cabal file,
which sounds like the wrong thing to do in the long-run.

Is there something that can be done on the hackage/ghc side to avoid this
issue? Or something less drastic than adding a template-haskell dependency
on my own package's cabal file?

Thanks,

-Levent.
