Ok, there is some weirdness with osx and safari and the names of 
downloaded files, which I rediscovered here:

http://www.ruby-forum.com/topic/141008

So I changed the filename on my Desktop to:

wxruby-2.0.0-universal-darwin-9.gem

(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.  So I guess you have your answer.
