[Haskell-cafe] build problems on Hackage

[Wolfgang Jeltsch]

Hello all,

alas, I couldn’t found any information about who is responsible for the build 
system on Hackage. So I address this issue to all of you.

type-level built fine with GHC 6.8 but failed to build with GHC 6.10. The last 
line of the build log is this:

> haddock: internal Haddock or GHC error: Maybe.fromJust: Nothing

The complete log is at <http://tinyurl.com/as67x5>.

This problem has the unfortunate consequence that type-equality-check cannot 
be built since it depends on type-level and nowadays only GHC 6.10 seems to 
be used for building packages on Hackage. This, in turn, will make almost all 
Grapefruit packages unbuildable when they are released (which is expected to 
happen soon). This, in turn, means almost no Grapefruit documentation on 
Hackage which, I think, would be very bad.

So could someone please take the time and fix this problem soon? Thank you in 
advance.

Best wishes,
Wolfgang
