PyQT bindings fail on Mac M1, MacOS 13.3 when using `pixi run rqt`

[etjones-erisyon]

I'm on a 2020 M1 MacBook Air, running MacOS 13.3. R

I ran pixi run rqt and got the following output:

[ $PROJ_DIR/turtlesim-pixi  $] pixi run rqt
 WARN pixi::project: can't find activation scripts: [".pixi/install/setup.sh"]
Could not import "pyqt" bindings of qt_gui_cpp library - so C++ plugins will not be available:
Traceback (most recent call last):
  File "$PROJ_DIR/turtlesim-pixi/.pixi/env/lib/python3.9/site-packages/qt_gui_cpp/cpp_binding_helper.py", line 43, in <module>
    from . import libqt_gui_cpp_sip
ImportError: dlopen($PROJ_DIR/turtlesim-pixi/.pixi/env/lib/python3.9/site-packages/qt_gui_cpp/libqt_gui_cpp_sip.cpython-39-darwin.so, 0x0002): symbol not found in flat namespace '__ZN10qt_gui_cpp12PluginBridge16staticMetaObjectE'

Populating font family aliases took 60 ms. Replace uses of missing font family ".AppleSystemUIFont" with one that exists to avoid this cost. 

This may or may not be related to missing activation scripts (Issue #3 )

The RQT window came up and loaded eventually, although it crashed as soon as I tried to add a plugin.
