I've downloaded SIP from the RiverSide homepage and compiled it statically (with python3 configure.py --static + make + sudo make install). I.e. I'm using the python3 binary (for configuration) that is installed from the official Python 3.4.3 installer.

I didn't even get to linking anything. All I wanted to do is to execute my PyQt application on the development machine itself (like a sanity check) before going to the next step: compiling a redistributable binary with pyqtdeploy.

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.

Since I was to make working redistributable applications using pyqtdeploy ONLY when having PyQt compiled statically, this was the reason why I compiled it statically. 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.
