nss-3.12 has been released yesterday, along with firefox-3.0. Firefox-3.0 should not depend on it's release candidate but on it's final release. I'll check if the ebuild of rc4 needs any changes to work with final. Reproducible: Always Steps to Reproduce:
I just successfully compiled nss-3.12 with the ebuild of nss-3.12_rc4. I assume, the tar.bz2 package of nss on the mirrors is created by the gentoo team, so I created my own tar.bz2 package out of the tar.gz package available from the download page which I changed the directory structure (removing the archives "first" directory) as the rcs' packages also have a differing structure.
In CVS, thanks, i'm going to fix the deps
