Is that a problem?

It is currently, because py2pack only parses There is a
pull request which fixes this:

It has been open since October 2013 :-/

As far as I
understand it, a requirements file is more for developing a set of
packages with versions known to work well in a certain
configuration--e.g. if you are deploying a web application with a
complex list of requirements that is only really tested with a
specific set of versions of those requirements, something of that

I think this behavior is by design.

If so, IMHO this design is broken because it excludes the pbr
approach, and the OpenStack community is a significant contributor to
the Python ecosystem:

Maybe the pbr approach is broken. I am rather fond of this post which explains why
requirements.txt perhaps should be used differently than

Very interesting, thanks for that link! It turns out that the post

The link to the corresponding Ruby post by Yehuda Katz is very
enlightening. IIUC, this highlights a deficiency in the Python
ecosystem's approach to packaging, due to the absence of any

But yes, I am beginning to come round to the idea that maybe pbr's
approach is broken.
