xmonad-0.14 build.log

Building xmobar-0.14 with USE="timezone" fails with the following error:

src/Plugins/DateZone.hs:1:13:
    Unsupported extension: DoAndIfThenElse

Looking around, this extension should require >=dev-lang/ghc-7.4.1 [1].

Yeah, it's one of haskell2010 features (ghc-7+).
I've raised lower bound unconditionally:

> 27 Jun 2012; Sergei Trofimovich <slyfox@gentoo.org> xmobar-0.14.ebuild:
> Raise lower bound to require ghc-7 (bug #419387 by Marco Paolone).

THanks for the report!
