Probably, ToGL library is not loaded to Tk interpreter. 
ToGL bridge for ruby requires to link the ToGL library to 
tcltklib (written on the 'README.euc' file). If the library 
cannot create as a loadable module, 'link to tcltklib' is the 
only way to use it on Ruby/Tk. But if your Tcl/Tk can load the 
library by 'package' command, you can use TkPackage module to 
load the library to Ruby/Tk. Please use TkPackage.require to 
load the library. If succeed, the library will be loaded and 
'togl' command will be defined on the Tk interpreter. After that, 
togl.rb will work fine. 

# I don't use the library. 
# So, I don't check whether the library works or not.
