That's not what I'm seeing on my system at least, I have Python 3.9
and info is in files, ie:

# ls -lah /usr/local/lib/python3.9/site-packages/xen-3.0-py3.9.egg-info
-rw-r--r--  1 root wheel  171B Apr 30 10:07 /usr/local/lib/python3.9/site-packages/xen-3.0-py3.9.egg-info

Do you have some kind of non-standard Python configuration?

If that's indeed the issue, at some point you will have to update to
Python 3.9 anyway.

Not sure, TBH I would expect it to "just work".  pkg builders seem
fine building the package with Python 3.9, so I wonder what's special
in your setup as to cause the build to fail.

I recommend you raise this on the freebsd-ports mailing list [0] and
Cc myself.  I'm sure there's something I'm missing on the xen-tools
plist file, but I have no idea what it is, and without being able to
reproduce the issue myself I have no way to debug.

Thanks, Roger.
