portage-2.1 installs /etc/make.conf.example in Gentoo-FreeBSD with: CHOST=i686-unknown-freebsd6.1 and it should be: CHOST=i686-gentoo-freebsd6.1 This is low prio, no revbump needed.
Well, that's what Diego gave me in his patch for bug 135241.
I suppose I can have some overseen now and then, don't I? ;) Sorry, I missed that CHOST detail before :(
This is fixed in svn r3504.
This has been released in 2.1.1_pre1.
