I finally got around to messing with this install again, and this time I 
was able to successfully install wxruby thanks to the advice given here. 
I installed the latest wxruby 2.0 instead of the version mentioned in my 
earlier posts.  I successfully installed the wxruby 2.0 gem which says 
it's for darwin-9 even though my system is darwin-8:

$ ruby -v
ruby 1.8.2 (2004-12-25) [universal-darwin8.0]


I got this error trying to install:

$ tar -xvf /Users/me/Desktop/wxruby-2.0.0-universal-darwin-9.gem.tar
data.tar.gz
tar: data.tar.gz: implausibly old time stamp 1969-12-31 17:00:00
metadata.gz
tar: metadata.gz: implausibly old time stamp 1969-12-31 17:00:00
$

so I changed the filename on my Desktop to:

wxruby-2.0.0-universal-darwin-9.gem

i.e. I removed the .tar extension on the end.  Then I changed 
directories
to my Desktop:

$ cd ~/Desktop

and then commanded:

~/Desktop$ gem install wxruby-2.0.0-universal-darwin-9.gem

and I immediately got a message that said wxruby installed successfully.
Wow that was fast.

Ok, now to test the install.  I found a basic wxruby example here:

http://book.opensourceproject.org.cn/lamp/ruby/cookbook/opensource/0596523696/rubyckbk-chp-21-sect-14.html

Instead of typing in the whole example, I decided to see if requiring
wxruby would work first.

r1test.rb
-------
require 'wxruby'


Nope:

r1test.rb:1:in `require': No such file to load -- wxruby (LoadError)
        from r1test.rb:1

Oh yeah, there's some ruby gem weirdness about requires.  Checking my
notes in pickaxe2, I came up with this:

require 'rubygems'
require 'wxruby'

Still didn't work:

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require': No such file to load -- wxruby (LoadError)
        from
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'
        from r1test.rb:2

Hmm...the basic example at the link above mentions a tutorial here:

http://wxruby.rubyforge.org/wiki/wiki.pl?Getting_Started

Ahh, the tutorial uses:

require 'wx'

Nope:

r1test.rb:1:in `require': No such file to load -- wx (LoadError)
        from r1test.rb:1

Ok, how about:

require 'rubygems'
require 'wx'

That worked.  On to the example:

require 'rubygems'
require 'wx'
include Wx

class TroutApp < App
  def on_init
    frame = Frame.new(nil, -1, "Title")
    text = StaticText.new(frame, -1, "You are a trout!",
              Point.new(-1, 1), DEFAULT_SIZE, ALIGN_CENTER)
    frame.show
  end
end

TroutApp.new.main_loop

And that worked.

Thanks for all the help.
