rubycocoa is the Ruby interface bindings to the native cocoa GUI  
toolkit of the Mac.
tcl is a scripting language and its standard GUI toolkit is tk that  
uses non native widgets - i.e. has its own unique look and feel.
tclTkAqua is the tcl Tk toolkit that uses native Mac widgets

The tk toolkit is widely ported and many other bindings to it have  
been produced, including Ruby.

If you are using rubycocoa then it doesn't make sense to me why you  
would want to use tcl, tk or  tckTkAqua as you are trying to mix  
different GUI toolkits.
