How about if you open `build/[prog_name]/COLLECT-00.toc` and find the entry for `libglib-2.0-0.dll`? Where is it being taken from?

So the work-around here is to unset `PYTHONPATH` before running PyInstaller.

Yes, PYTHONPATH is automatically added to `sys.path`, as [per docs](https://docs.python.org/3/library/sys.html#sys.path). In your case, it's been set by Csound installer (presumably you installed/upgraded it three times). Running `export PYTHONPATH=` in your...

The difference is probably indeed coming from python interpreter not using `sys.path` / `PYTHONPATH` for shared library resolution. Not sure why we search `sys.path` first, but it seems very deliberate...

Yeah, unfortunately the current support for QtWebEngine on macOS is [rather messy](https://github.com/pyinstaller/pyinstaller/blob/c95dba86673cba819558a0c6218e934095d87ac9/PyInstaller/utils/hooks/qt.py#L738-L762), to put it charitably. What's worse is that properly fixing it (i.e., preserving the original frameworks' layout) is...
