Please pardon this question, but how did you extract the above information?

When I use a fairly universal method (please see below), I do find 
essentially the same precise64 ... information, but not the RPM version.

[ykarant@jb344 Downloads]$ strings 
google-chrome-stable_current_x86_64.rpm | grep -i build
precise64build3.chrome.corp.google.com
[ykarant@jb344 Downloads]$ strings 
google-chrome-stable_current_x86_64.rpm | grep -i version
Version: GnuPG v1.4.2.2 (GNU/Linux)
   # not anticipate a new version of bzip2 with a different
   # minor version number anytime soon.
