I remembered and also figured it out what to do.

The existing package does not work any more with some unresolved symbols.

The RubyTk requires pthreads:
  https://blogs.oracle.com/prashant/entry/ruby_and_enable_pthreads
enable pthreads is 30-50% down in performance on Ruby, solution is to use
this patch which disables switching ucontext with enabled pthreads:

I’ll add that, respin, test and push.


Best regards
