I'd love to move PyPy support forward (I even went to the trouble of doing the password-reset dance necessary to get my SSH keys onto these buildbots), but it looks like we have installed from the PPA, which has fallen behind the official releases -
https://launchpad.net/~pypy/+archive/ubuntu/ppa/+packages - so upgrading isn't obvious.
Weirdly it looks like Debian is on top of things and
does have a current version of the package -
https://packages.debian.org/sid/pypy - but I have no clue how to configure these machines to pull just this one package from Debian. If anyone knows how this works, I'd be happy to put more SSH keys on these servers.
