Comment 4 for bug 771489

I ran into this same problem trying to build Nova on Red Hat 6.1 (x86_64) regardless of having python-distutils-extra = 2.19 installed. Removing python-distutils-extra and applying the referenced patch (https://code.launchpad.net/~jaypipes/nova/bug771489/+merge/59135) fixed the issue. Are there differences between python-distutils-extra 2.18 and up that would have broken this?
