Created attachment 481808 [details, diff] pkginfo.patch At present, the pkginfo ebuild attempts to use replace sphinx-build with hardcoded /usr/bin/sphinx-build, which is not necessary. In fact, it breaks Prefix. I propose the attached patch to remove this hack without revision bump. If there is no objection, I will go ahead and commit it in a week. Thanks!
Makes sense, just kill it.
committed. Thanks.
