I have been shuttling ideas back and forth between the IronPython and Ubuntu
This is the latest exchange. I have added comments...

Jeff has corrected my error here, and both the 2.7 branch and the tarball
are up to date. -- VC

This may still be a sticky spot. The tarball does contain IronRuby, but
There must be a version identifier somewhere, but it is not obvious. The
only Ruby version number I found when hunting around this afternoon was in
an .html file, and the version number was 0.1! I'm pretty sure that is
Perhaps the README file at the IronLanguages root should be edited to
document the versions of the contents, or maybe a NEWS file could be added.
And, why does Rogers say "unless we have two different source packages"?
Methinks another round of mail exchanges may be needed here.
