Created attachment 348370 [details] build.log gnome-doc-utils-0.20.10-r1 failed to build when first install seems something wrong with xml2po When update from old version(0.20.10), it's ok since it loads xml2po from the old installation in the system. And 0.20.10 seems fine.
Are you sure you are using latest ebuild? 10 May 2013; Gilles Dartiguelongue <eva@gentoo.org> gnome-doc-utils-0.20.10-r1.ebuild, +files/gnome-doc-utils-0.20.10-fix-out-of-tree-build.patch: Make build system stop using installed xml2po, bug #463698.
sorry, using the latest ebuild and it's fine.
