Code review comment for lp:~gary/lazr.delegates/fixbuild

This does the usual dance that we've done lately to fix our lazr builds: remove some build dependencies and get the version number from a file.

We also should move trunk from pqm to lazr-developers.

I need a release of this branch to merge my launchpad branch that uses all of our newest lazr releases (lp:~gary/launchpad/lazr-dist).
