Created attachment 262971 [details] build.log
Also I can compile polkit only with MAKEOPTS="-j1". Something wrong in these man pages.
Please do not mix two different issues in a single bug. If you see parallel make failures, report a separate bug.
+ 14 May 2011; Gilles Dartiguelongue <eva@gentoo.org> polkit-0.101-r1.ebuild: + Add missing dtd to DEPEND, bug #355505. Although the absence of network and the dtd itself didn't cause the build to fail here, it is still correct to add the dependency. Thanks for reporting.
