frescobaldi2 @2.20.0: Launch error: ModuleNotFoundError: No module named 'PyQt4'

[coffeyjj]

Computer: Apple iMac7,1 *OS: OSX 10.11.6 (El Capitan)* Xcode: 8.2.1 (compatible with El Capitan)

port install Frescobaldi2 completed with no errors, BUT terminal output for the launch attempt indicates the Frescobaldi app fails to launch due to a missing module:

ModuleNotFoundError: No module named 'PyQt4'

Terminal output for Frescobaldi2 launch attempt:

iMac:~ Admin$ /Applications/MacPorts/Frescobaldi.app/Contents/MacOS/Frescobaldi

See the py2app website for debugging launch issues

FULL terminal output IS ATTACHED for BOTH Frescobaldi2 port installation AND Frescobaldi app launch attempt.

NOTE:

The Py2App website provides NO USEFUL HELP for debugging this launch issue; just some cryptic text intended for people who do this every day and ALREADY know what to do.

For example, on the Py2App page "Debugging application building"(​https://py2app.readthedocs.io/en/latest/debugging.html), only this cryptic text below is offered with NO INDICATION at all PRECISELY HOW one is supposed to actually use the suggested context-free, example-free, effectiveness-free suggestion to "use --includes or --packages" to "add the missing module to the application."

Some common problems are:

An import statement fails due to a missing module or package

This generally happens when the dependency cannot be found by the source code analyzer, either due to dynamic imports (using __import__() or importlib to load a module), or due to imports in a C extension.

In both cases use --includes or --packages to add the missing module to the application.

If this is needed for a project on PyPI: Please file a bug on GitHub, that way we can teach py2app to do the right thing.

I have absolutely NO IDEA what a Py2App "import statement" is, or precisely what Py2App is trying (in its maximally ineffective manner) to tell me to do here in order to resolve my Frescobaldi launch failure. None.

Nor does any of this, as far as I know, have anything to do with "a project on PyPI," whatever that is, so the clear implication of the Py2App text above is that I'm definitely NOT to file a bug on Py2App's Github site since none of this is needed for a PyPI project, whatever that is.

I could find absolutely nothing on the Py2App website that would help me resolve this Frescobaldi port launch issue.

Help please.

For me, on macOS 12, the app launches, but the Music View on the right of the main window displays only the message "Could not load the ​popplerqt4 module."
