Multiple versions within a single package slot have been !!! pulled into the dependency graph: ('ebuild', '/', 'dev-db/mysql-5.0.26-r2', 'merge') pulled in by ('ebuild', '/', 'virtual/mysql-5.0', 'merge') ('ebuild', '/', 'dev-db/mysql-4.0.27-r1', 'merge') (no parents) Reproducible: Always Steps to Reproduce: 1. Fresh install 2. emerge -av =dev-db/mysql-4.0.27-r1 3.
This will show us what's pulling it in: emerge -pt =dev-db/mysql-4.0.27-r1

Yes, this is a very long standing bug. If you want mysql-4 then you'll have to mask mysql-5: echo ">=virtual/mysql-5" >> /etc/portage/package.mask *** This bug has been marked as a duplicate of bug 1343 ***
(In reply to comment #3) > echo ">=virtual/mysql-5" >> /etc/portage/package.mask You also have to mask >=dev-db/mysql-5 if dev-db/mysql is in your world file or something depends on it, otherwise you'll get a similar error when you update your system. Even if bug 1343 is fixed, there's still no support for a versioned atom in the world file. We should have support for something like that in the near future though (bug 144480).
