Problem using wxRuby

I am trying to create my first GUI using wxRuby. I installed wxRuby (using gem install wxruby-ruby19) and, it seemed to be installed alright. I copied some code directly from the wxRuby site. Here is the code I used:

test.rb

require "wx"
include Wx

class MinimalApp < App
  def on_init
    Frame.new(nil, -1, "The Bare Minimum").show()
  end
end

MinimalApp.new.main_loop

When I ran it, I got this error:

<internal:lib/rubygems/custom_require>:29:in `require': libwx_gtk2u_stc-2.8.so.0: cannot open shared object file: No such file or directory - /usr/local/ruby/lib/ruby/gems/1.9.1/gems/wxruby-ruby19-2.0.1-x86-linux/lib/wxruby2.so (LoadError)
from <internal:lib/rubygems/custom_require>:29:in `require'
from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/wxruby-ruby19-2.0.1-x86-linux/lib/wx.rb:12:in `<top (required)>'
from <internal:lib/rubygems/custom_require>:33:in `require'
from <internal:lib/rubygems/custom_require>:33:in `rescue in require'
from <internal:lib/rubygems/custom_require>:29:in `require'
from test.rb:2:in `<main>'

I thought it was saying that wxruby wasn't in that directory, but I checked and it was, so I'm not sure what the problem is. If anyone could help, that would be awesome.

I tried the same thing and got the same result.

It turns out that there are 2 wxRuby gems. If you are using Ruby 1.9x, you want wxRuby-ruby19. (gem install wxruby-ruby19).

I uninstalled the wxruby gem that I installed the first time (gem uninstall wxruby), and then installed the gem for my version of Ruby (gem install wxruby-ruby19). And Voila! All the sample code just worked. No additional downloads needed.

To use wxRuby you need wxWidgets installed (wxGTK in your case). The problem is wxRuby uses the wxWidgets shared libraries (e.g. libwx_gtk2u_stc-2.8.so.0) and it cant find them.
