I had to drop your keywords because I don't have amd64 installed. See bug #152924 for what was done. Keyword these: dev-java/mx4j-core dev-java/mx4j-tools =dev-java/mx4j-3.0.1-r2
I migrated stuff to use mx4j/core so you need to readd your keywords to the following too: dev-java/commons-modeler-1.1-r3 www-servers/tomcat-5.5.20-r3 I will probably do dev-db/c-jdbc after you have keyworded as there is no reason for a revision bump there as it uses both -core and -tools.
All done.
