Perl USE flag haserecently been turned off globally, x11-terms/rxvt-unicode needs it in order to have tabbed terminals. Please add perl to IUSE defaults (see [250179#c16]) Reproducible: Always
Probably no, the tabs are features which can be enabled optionally. Lets see what the maintainers say.
From README.configure: --enable-perl (default: on) Enable an embedded perl interpreter. See the rxvtperl(3) manpage for more info on this feature, or the files in src/perl/ for the extensions that are installed by default. The perl interpreter that is used can be specified via the "PERL" environment variable when running configure. Even when compiled in, perl will *not* be initialised when all extensions have been disabled "-pe "" --perl-ext-common """, so it should be safe to enable from a resource standpoint. (In reply to comment #1) > Probably no, the tabs are features which can be enabled optionally. USE=perl enables more features than just tabs. :) Since upstream likes it to be on by default, I guess we should follow that. Enabled in all ebuilds and described specially in metadata.xml.
