 tcltklib.rb is 

pigeon% cat tcltklib.rb
require 'tcltklib' +
  case ENV['TCL_LIBRARY']
  when /8\.(\d)/
    '8' + $1
  when /7\.6/
    '76'
  end
pigeon% 


 Do you have defined the environment variable TCL_LIBRARY ?

 You have 4 libraries 

pigeon% ls tcl*dll    
tcltklib76.dll  tcltklib81.dll  tcltklib82.dll  tcltklib83.dll
pigeon%
