[PyQt] PyQt5 error with Qt 5.13.x

[Maik Schmidt]

Hi all,

I've been trying to install the latest PyQt5 version with an underlying 
Qt 5.13.1, but when importing

PyQt5.QtCore

I keep getting the error:

ImportError: 
/sw/installed/PyQt5/5.14.1-GCCcore-8.3.0-Python-3.7.4/lib/python3.7/site-packages/PyQt5/QtCore.so: 
undefined symbol: _ZN8qfloat1613mantissatableE

And indeed, I cannot find the symbol qfloat16::mantissatable in Qt 
5.13.x versions anymore, while in Qt 5.12.x, it is still present.

So, is this an incompatibility of PyQt5 itself or is there something 
wrong with my Qt installation?

Any help would be much appreciated!

Best,

Maik
