leap 15 Pure Data fails to launch

Hi
Starting pd in leap 15 gives this error:

Error in startup script: couldn’t read file “/usr/tcl//pd-gui.tcl”: no
such file or directory
^CPd: signal 2

It used to work in 42.3 (when using the pd-extended package which is not
in the repos for Leap 15)
Any ideas?
