Comment 10 for bug 307462

I built ruby1.8 with the following patch:

It built fine, but when loading tk:
irb(main):002:0> require 'tk'
/usr/lib/ruby/1.8/tk.rb:1127: warning: Inconsistency. Loaded Tcl/Tk libraries are enabled nativethread-support. But `tcltklib' is not. The inconsistency causes SEGV or other troubles frequently.
=> true
irb(main):003:0>

It seems that the only option would be to drop ruby-tk support.
