Kopete depends of ~net-libs/ortp-0.7.1-r1 but net-libs/ortp-0.11.0 exists. Why not delete the "-0.7.1-r1" in the kopete ebuild ?
Because it's package.masked and kopete won't compile with it. $ grep -C2 ortp /usr/portage/profiles/package.mask # Stefan Schweizer <genstef@gentoo.org> (05 May 2006) # kopete needs ~0.7.1, mask newer versions to avoid up/downgrade cycles >=net-libs/ortp-0.8
