Apparently, quite recently, a new version of setuptools was released
that eliminated the Feature class.  From what I understand, the class
has been deprecated for quite a while, but the removal still seems to
have taken some consumers by surprise; we discovered it when a package
that uses MarkupSafe failed tests with the same error today.  We may
have to consider a short-term pin to the version of setuptools (if
that's even possible) on projects that encounter the problem…
