We should avoid hard-coding the version string with something like
"/lib/pulse-" ,version "/modules"

Overall LGTM for staging. Maybe you already did this but I recommend
comparing the built outputs of the old and new versions to make sure we
don't accidentally lose any components by using the new build system.
