I installed layman by doing "emerge layman" which pulled in a few packages. The tool didn't work, however, a "layman -L" which should list all available overlays just listed one. Luckily when I did a "layman -a" it gave an error message telling me it couldn't find svn, so I knew it needed it. After emerging subversion seperately, everything works. So the ebuild just needs to list subversion as a dependency and everything should be golden.
Steps to Reproduce:
1. emerge layman (not having subversion installed)
2. layman -L
only 1 overlay listed
a long list of overlays should listed
