Code review comment for lp://staging/~gary/lazr.batchnavigator/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 lacr-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).
