My apologies. I'm glad to see that someone has considered these issues 
and that java and node.js are only build/dev dependencies. I'm pleased 
to meet another hybrid admin+developer ;)

I hope that my buildbot puppet module helps in some way. I have a 
working Vagrant setup to build and install buildbot 0.8 from git. I'm 
willing to share any of this.
