none of the tools you quote work well for the scipy community (where I am coming from). There are several reasons for that: - complex compilation is a drag with distutils - virtualenv is not very useful as usually advocated, because you do not want separate environment. You want everything in the same python. - generally, working with distutils code is just a big pain. I have dealt for years with it, and from my experience, anything short of a rewrite from scratch won't solve our issues.
