Hi,all!  
I’ve installed Tk for GUI apps in Ruby. I was getting errors for  
require ‘tk’,  
then I’ve installed libtcltk-ruby and everything run well. BUT, this is  
what I get for  
require ‘tkextlib/tile’:

/usr/lib/ruby/1.8/tk/package.rb:86:in `require': TkPackage can't find package tile (RuntimeError) from /usr/lib/ruby/1.8/tkextlib/tile.rb:24 from converter.rb:2:in`require’  
from converter.rb:2

I guess there are some packages missing or what? Help. Thanks!

You don’t need to modify your installed Ruby.  
There is no Tile extension installed for your _Tcl/Tk_.  
Tile extension is a standard part of Tcl/Tk8.5 or later,  
but is not a standard part of Tcl/Tk8.4.  
If your Tcl/Tk version is 8.4.x, You must install Tile extension  
for your Tcl/Tk.

# ActiveTcl-8.4 package includes Tile extension.

Ruby/Tk uses Tcl/Tk libraries. So, Ruby/Tk can use all Tcl/Tk  
extensions, if the extension is installed.  
The output of “ruby /usr/lib/ruby/1.8/tkextlib/pkg\_cheker.rb”  
may be useful.
