[Haskell-cafe] Hackage bug? Autobuild failure on literate source with ignored code blocks.

In that case, I'll update my code and the wiki to use an alternative code style.

Since Hackage is using an unstable development build of Cabal, I'd
like to force it to use a released version to prevent such an issue
from occurring again. I've added the following line to my .cabal file:

cabal-version: >= 1.6 && < 1.7

However, when testing with Cabal 1.7.3 (which is the version used by
Hackage), I am warned that:

-------------
Warning: dbus-core.cabal: This package requires Cabal version: >=1.6 && <1.7
Distribution quality errors:
This package requires Cabal version: >=1.6 && <1.7
Note: the public hackage server would reject this package.
-------------

Does this mean that it's impossible to require an earlier version of
Cabal in Hackage-published packages? If so, the use of a development
version of Cabal in the auto-build system seems unwise.
