Just renaming the old *-0.2.3.ebuild didn't work, see: http://bugs.gentoo.org/show_bug.cgi?id=38807#c2 because of a small bug in src/racoon/Makefile.in Reproducible: Always Steps to Reproduce:
Created attachment 24733 [details] ipsec-tools-0.2.4.ebuild This ebuild fixes the above mentioned bug directly with the help of sed, so no patch is needed.
I'm closing this as fixed as 0.2.4 is in Portage already; I just manually dosbin'ed the racoon executable instead.
