Non-standard libs can't be bundled in macOS

It's not possible to bundle nonstandard libs into the macOS wheel currently (libyaml, libpcre, ...) due to a limitation in delocate described in matthew-brett/delocate#12 (comment) unless the pyuwsgi shared lib is placed inside a dummy package. It may make more sense to fix delocate rather than pyuwsgi, however.

Fundamentally this is a delocate limitation (it works with auditwheel) and maybe @matthew-brett has some ideas on how feasible implementing support for it would be. I'm motivated to contribute time, if that helps. 😄

Alternatively, we can put pyuwsgi into an actual package namespace, I've tried this out in my pyuwsgi-package branch and it works (at least enough to execute) for Python 3 but breaks C extension module initialization for Python 2.7. But I've only put about 15 minutes into this, so that's presumably fixable.

Yes, it should be easy-ish - if you'd like to help, I'm sure we can get it done in a day or so.

[natefoo]

Great, thanks for responding! I'll have a look, then.

Just for future reference, work on it is here: matthew-brett/delocate#39

Hoping this gets resolved upstream soon, but in the meantime, you probably want to build the MacOS pyuwsgi wheels locally (unless you have all the necessary libraries installed) via:

pip install --no-binary=pyuwsgi pyuwsgi

I setup @natefoo's fork in de3635c and released it on PyPI as 2.0.17.2b4.
