Probably you can get BWidget extension from ActiveTcl package.
Please copy BWidget library files on ActiveTcl to your Tcl/Tk (which is
used on your Ruby/Tk) library path.

Please try to run <ruby-lib-path>/tkextlib/pkg_checker.rb.
It will show which extension is available on your Ruby/Tk.

You can get a pure Ruby/Tk (with standard Tcl/Tk only) version of 
progressbar widget class (progressbar.rb) at
<http://www.dumbo.ai.kyutech.ac.jp/~nagai/RubyTk/?%A4%BD%A4%CE%C2%BE%A4%CE%A5%B5%A5%F3%A5%D7%A5%EB%A5%B9%A5%AF%A5%EA%A5%D7%A5%C8>
(the page is written in Japanese).
It is an example of usage of place geometry manager and how to make a 
composite widget class.
