I use sets to deal with this, so much simpler to organise than a single world file. If I am installing something from outside of portage and it has dependencies, I create a set listing those dependencies and emerge that set. If I remove the package I can remove the set and depclean will unmerge anything not needed by other packages. For example, I use a perl script called zenus (specific to my ISP) and /etc/portage/sets/zenus-deps contains dev-perl/SOAP-Lite perl-gcpan/SOAP-DateTime dev-perl/Class-Inspector dev-perl/Data-Dumper-Concise Those packages may or may not be needed by anything else, but a set means I keep them installed without cluttering world. I do similar for specific projects, especially short term ones so I can clean up after. -- Neil Bothwick Committee (noun): A group of people spending hours taking minutes
