I wrapped the PYTHONPATH around the various provided python tools.
I also found a spare path that required patching.
I am not sure this fixes every tool but I did get a few to work now.

Thanks for attaching guix-patches.

I also added debugfs as a requirement for a bpf system.  To use it
%bpf-file-systems can be used in place of %base-file-systems in the
operating system definition.

Thanks,

John
