 That’s quite an improvement, to say the least.

 If you don’t want to test a bunch of system versions (a reasonable
 decision, for sure), you might just want to declare a build dependency on
 `bin:python2.7:python27` and make sure the build programs use `python2.7`.
 Off the top of my head, I don’t know which OS versions come with which
 Python versions.
