tk should set TCLLIBPATH

[JensTimmerman]

TCLLIBPATH should be set to $root/lib in all tk easyconfig's, so probably use modextrapaths

[nathanhaigh]

I just came across this issue while getting an easyconfig file ready for staden. Gap5 complained about not being able to find Tk. Turns out that Tcl's auto_path didn't include Tk's lib/tk8.6 dir. To fix this i set TCLLIBPATH to lib/tk8.6 using modextrapaths in the Tk easyconfig. Hope to submit the staden pr in due course.

I can't believe this almost 10-year old report contains a solution to something I'm still seeing in 2024...

This probably means that tk wasn't installed properly.

Okay, so the easyconfig is still missing the necessary TCLLIBPATH entry. Will see if I can create a pull request

thanks for looking at this @Micket this was a reminder I made for myself after finding the issue and the solution, and then seem to have never followed up on.

Turns out it needs a framework fix as well, custom delimiter for TCLLLIBPATH https://github.com/easybuilders/easybuild-framework/pull/4487
