trouble installing Tkx

There's a bug #115662 for Tkx on rt.cpan.org that was opened three
years ago with no response. I appended my log to it yesterday, since I
seem to be encountering the same problem with newer software (I'm on
openSUSE Leap 15.0)

I'd appreciate any suggestions. Let me know if you need any more
information.

Thanks and regards,
