Subject: sys-apps/i2c-tools: add missing perl dep and make it optional
X-Git-Url: http://git.tremily.us/gitweb.cgi?a=commitdiff_plain;h=e88a25e039c7faed7d97a5e19fed9e15dcb0b36d;p=gentoo.git

sys-apps/i2c-tools: add missing perl dep and make it optional

This package installs a number of perl scripts, so make sure we RDEPEND
on perl to avoid broken deps.  But also put that behind USE=perl so we
can install the other (more interesting) programs w/out forcing perl on
everyone.
