Looks like it's one of those useful packages that doesn't quite make it into @system, but is pulled in as a dep from all sorts of interesting places. Here I get: $ equery depends bc * These packages depend on bc: dev-libs/openssl-0.9.8y (test ? sys-devel/bc) dev-libs/openssl-1.0.1e (test ? sys-devel/bc) net-print/cups-filters-1.0.29-r1 (sys-devel/bc) sci-geosciences/gpsd-3.7 (test ? sys-devel/bc) x11-misc/xscreensaver-5.20 (sys-devel/bc) A useful trick I use on my Gentoo test/dev vms is a defined set called @tools. These all use a shared /etc/portage/ for consistency, so add bc to the set and it is merged everywhere. This helps keep my world free of clutter. -- Alan McKinnon [email protected]
