pyqtgraph importlib ModuleNotFoundError issue

… or maybe it is just an importlib issue

Trying to compile minimalistic pyqtgraph(PyQt5) application (pyqtgraph_minimal.py):

from pyqtgraph import plot, exec

win = plot()
win.setWindowTitle('pyqtgraph example')

if __name__ == '__main__':
    exec()

with

python3 -m nuitka --plugin-enable=numpy --plugin-enable=pyqt5 --onefile pyqtgraph_minimal.py

in clean virtualenv, having latest packages available through pip, pip3 list output:

Package    Version
---------- --------
Nuitka     0.6.17.1
numpy      1.21.2
pip        21.2.4
PyQt5      5.15.4
PyQt5-Qt5  5.15.2
PyQt5-sip  12.9.0
pyqtgraph  0.12.2
setuptools 58.1.0
wheel      0.37.0

but getting (maybe import) error after application start:

Current Nuitka develop needs no import help anymore, so that is fantastic news.

Yes, that is what it is about. Nuitka now resolves the code that computes this at compile time and only includes them if they are necessary. And switching bindings is of course easy then too.
