Running Frescobaldi 3 on OSX?

[Henning Hraban Ramm]

Hi,

I guess *someone* did manage to compile Frescobaldi 3.x on a Mac.
I juggled around with PyQT, MacPorts and Homebrew and didn’t succeed for a long 
time, there was always at least one of the many dependencies missing or not 
compiling. (First on OSX 10.9.5, now on 10.14.6)

Now it looks like I got everything with MacPorts, but if I call the frescobaldi 
script from the egg, I get:

$

One of the two will be used. Which one is undefined.

ValueError: PyCapsule_GetPointer called with incorrect name


If I remove (hide, rename) one of the two QtCore instances, it fails earlier, 
because something’s missing:

ModuleNotFoundError: No module named 'PyQt5.QtWebKitWidgets'

or

ImportError: 
dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/PyQt5/QtCore.so,
 2): Library not loaded: @rpath/QtCore.framework/Versions/5/QtCore
  Referenced from: 
/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/PyQt5/QtCore.so


Of course I also tried to run the python scripts from 
site-packages/frescobaldi_app, but it seems they’re not meant for running.

What to do?
