Sincerely, I'd consider this an ebuild that should be removed, replaced instead by some l7-filter-sources that actually does the patch at the right time: Detected file collision(s): /usr/src/linux-2.6.27-gentoo-r7/net/netfilter/nf_conntrack_core.c /usr/src/linux-2.6.27-gentoo-r7/net/netfilter/nf_conntrack_standalone.c /usr/src/linux-2.6.27-gentoo-r7/net/netfilter/Makefile /usr/src/linux-2.6.27-gentoo-r7/net/netfilter/Kconfig /usr/src/linux-2.6.27-gentoo-r7/include/net/netfilter/nf_conntrack.h Searching all installed packages for file collisions...

This was already even announced: http://archives.gentoo.org/gentoo-dev-announce/msg_0d7c089ea38747a1dedfb2019e02d5a2.xml Package masked now.
Gone.
