It shows that your Tcl/Tk libraries linked with Ruby don't load 
(or fail to load) the tktree library (or definitions). 
Or your Tcl/Tk libraries are too old and don't support namespaces. 

If your Tcl/Tk cannot autoload the tktree library, you must load 
the library to Tcl/Tk interpreter working under Ruby/Tk when 
requiring tktree.rb.

#  
# Of cource, <Tcl script file> is your tktree.tcl file.
