Problems with Linuxcnc 2.9.4 and GladeVCP

$ cd configs/sim/axis/gladevcp
$ linuxcnc gladevcp_panel.ini

I get all kinds of errors and will not load.  I am trying to learn gladevcp and its just not even loading.  The line in the gladevcp_panel.ini file that loads gladevcp is:

GLADEVCP= -u hitcounter.py manual-example.ui

Is there a problem with this line. I feel that the version of linuxcnc 2.9.4 (debian Trixie) does not support these example files but nowhere on the internet have I found confirmation to this.  Please let me know as I have already wasted too much time with this.

thanks,
AC
