We're still shipping speex-1.2_rc1
Speex is still at rc2. However since that version the package was split to Speex and SpeexDSP. It's only SpeexDSP that is at rc3.
Thanks, this was fixed in git by Aric Belsito. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2776a627b16b7a06060cd2d563a77f35680f9910
