Comment 10 for bug 2005955

I have isolated the issue.

The empty directory gets created when running the line QApplication.instance().processEvents(QEventLoop.ProcessEventsFlag.ExcludeUserInputEvents) in src/calibre/utils/rapydscript.py

This happens when compiling things with the included rapydscript compiler. Maybe using an external compiler can work around the issue, but at present there is no rapydscript compiler included in the ports tree.

For the time being I'm just cleaning after myself, as not to trigger warnings and failures due to failed checks. I can improve things later.
