Although the ebuild specifies a dependency >=dev-lang/ghc-6.10.4
as per this thread http://forums.gentoo.org/viewtopic-p-7249056.html#7249056
it seems it still needs >=dev-lang/ghc-7
The strange this is that older ebuilds (xmobar-0.14) contained a dependency >=dev-lang/ghc-7.0.1
Steps to Reproduce:
1. emerge xmobar with stable ghc
Created attachment 339216 [details]
The build fails at the end with
src/Xmobar.hs:170:16: Not in scope: `void'
still happens with x11-misc/xmobar-0.16-r1
as we have ghc-7.4.2 stabilized and this update solves problem, so I mark this bug as wontfix. Sorry for such a slow reaction.
