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

[Levent Erkok]

Thanks Alexander.. Here's the shocker: I just checked that page again (
http://hackage.haskell.org/package/sbv) and now it's mysteriously fine!
Hackage must've recompiled the package somehow. Someone watching this
thread must've fixed something on the server and triggered a new compile.

While I'm happy the problem is now gone, the mystery behind the hackage
recompile remains.. Maybe someone can shed some light on how hackage goes
about managing the uploads.

-Levent.
