$ ruby widget  
/usr/local/lib/ruby/site\_ruby/1.8/tk.rb:3339:in `_symbolkey2str': hash modified (RuntimeError) from /usr/local/lib/ruby/site_ruby/1.8/tk.rb:3339:in`initialize’  
from /usr/local/lib/ruby/site\_ruby/1.8/tk/root.rb:36:in `new’  
from widget:27

the “widget” is from ext/tk/sample/demos-en. This is ruby 1.8.4, linux.

What have I messed up??

Probably, there are libraries based on ruby-1.8.2 in  
“/usr/local/lib/ruby/site\_ruby”.  
tkutil.so is not compatible between ruby-1.8.2 and 1.8.4.  
If ruby-1.8.4 loads ruby-1.8.2’s tkutil.so, such error is  
produced.

That was it. Thanks! I cleared all the tk and tcl files from my  
site\_ruby.
