Hi, this is a known issue. The buildbot-www package cannot be integrated in Debian due to tons of missing JS dependencies. See buildbot(7) and bug #883529 for more details.
Since then, buildbot has changed from coffeescript+gulp to plain JS+webpack. This should make it easier to package the missing dependencies and support packaging the www plugins. Still far from a trivial task unfortunately... I am not even sure how to proceed. I would really appreciate some help on the matter. In the meantime, you may install buildbot-www via pip (although this is not a very nice workaround). Thanks.
