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.
