There is no next step. You can only use a static PyQt in a compiled binary.

>>> The issue is that I can't really develop Python code this way. My IDE (PyCharm) claims that there is nothing in the PyQt5 package in site-packages. The directory is there, in /LIbrary/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/PyQt5. It contains an __init__.py, a bunch of .a library files and the uic directory with lots of other stuff". But references such as PyQt5.WtWidgets can't be resolved.

I'm beginning to think that in order to be able to run my PyQt application (On the development machine) AND to be able to make a build using pyqtdeploy, I need to built PyQt5 twice, the statically AND dynamically linked version.

That's what most people would do.
