Created attachment 437372 [details, diff] Patch that fixes the problem by passing localedir to compile step (I'm a maintainer of Newsbeuter, and also Funtoo user.) When compiling Newsbeuter, Gentoo doesn't set `localedir` to path where locale files will reside after installation. Since `localedir` value is hard-coded into the binary, installed version can't find locale files. Please see an attachment for a Git patch that fixes this (made against Funtoo ports as I don't have Gentoo ones—sorry about that.)
thank you for report with the patch.
Fixed in 2.9-r1.
