If you want to use Ruby/Tk (tk.rb and so on), you must have tcltklib.so 
which is working correctly. When you have some troubles on compiling, 
please read README.tcltklib and README.ActiveTcl. 
Even if there is a tcltklib.so on your Ruby library directry, it will not 
work without Tcl/Tk libraries (e.g. libtcl8.4.so) on your environment. 
You must also check that your Tcl/Tk is installed properly.
