[Nix-dev] Rev. 27611 (applyGlobalOverrides)

[Yury G. Kudryashov]

Hi!

I've used applyGlobalOverrides in kde4x for the following reason.

Some parts of the official KDE releases depend on external packages (e.g., 
libktorrent, kdevplatform). Now kde47.kdenetwork will use libktorrent built 
against kdelibs-4.5.

We have two solutions.
 * applyGlobalOverrides;
 * manually override quite a few packages in 'callPackage kde4x' call.

Any volunteers for the second way? Any other ideas?
