Some Boost developers have started and maintain ryppl (as reported in http://lists.boost.org/boost-cmake/2010/08/0924.php), which may correspond (partly) to what you are looking for:
http://ryppl.org/
http://ryppl.github.com/
http://github.com/boost-lib/

Then, of course, there are the tools used by Fedora. To name a few, Mock, Koji, Bodhi, Mash, TurboGears, Git, Trac, FedPkg. And, for the virtual machines, Xen is apparently used.
