Re: build of ghc 7.4.0 from debian experimental succeeds, but can't install resulting ghc-doc package

[David Fox <ddssff@gmail.com>]

So I guess we need a patch to haskell-devscripts like the one attached.

Dear David,

yes, this is correct. Previously, --interface-version was added by me to
the Debian package, to expose the number in the first place:
http://patch-tracker.debian.org/patch/series/view/ghc/7.0.4-8/haddock-expose-interface-version
There, the result includes the prefix "haddock-interface-".

Upstream adopted the patch, but dropped the prefix:

Greetings,
Joachim
