There are some tests in util-linux that seem to require the presence of the "bc" calculator, but it's not a dependency. You can grep through these scripts: tests/ts/ipcs/functions.sh tests/ts/hwclock/systohc Simply re-emerging util-linux with FEATURES="test" is not actually re-running all of the tests on one of my boxes. But the other machine does run tests when upgrading from 2.21.2 to 2.22.2. So you might have to downgrade + reupgrade to reproduce the problem. If you do get the tests to run, it should be fairly easy to see the bc "command not found" message. Reproducible: Always
should be all set now in the tree; thanks for the report! Commit message: Pull in sys-devel/bc for USE=test http://sources.gentoo.org/sys-apps/util-linux/util-linux-2.22.2.ebuild?r1=1.13&r2=1.14 http://sources.gentoo.org/sys-apps/util-linux/util-linux-9999.ebuild?r1=1.39&r2=1.40
