Subject: fxruby gem problem

Dear ruby acolytes

ruby 1.8.5

I am floundering here, again.
Having more or less decided to switch from rubytk to fxruby I have
installed FOX and the fxruby-1.4.7 gem in Mandriva 2007.  The simple
test program from David Berube's book Practical Ruby Gems does not
work.  In fact none of the package test examples will run either.  They all
fall down trying to load fox14.  This is my test script:
-------------------------------------------------------------------
require 'fox14'

include Fox

zeg = FXApp.new

fen = FXMainWindow.new( zeg, "Test app" )

abutton = FXButton.new( fen, 'Click me!' )
abutton.connect( SEL_COMMAND ) do
  abutton.text = "I've been clicked!"
end

zeg.create
fen.show( PLACEMENT_SCREEN )
zeg.run
-------------------------------------------------------------------
and the error is:
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- fox14 (LoadError)
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'
        from zeg.rb:2

The gem search path is:
/usr/lib/ruby/gems/1.8/gems/fxruby-1.4.7
and the target is lib/fox14 which certainly exists and contains a
number of ruby scripts; aliases.rb, calendar.rb, core.rb, etc.

It looks like ruby is trying to load the directory as a file, perhaps
as fox14.rb.  Does anybody know what causes this behaviour?  All the 
available fxruby scripts seem to imply that fox14 should be acceptable
as a target.  Is there some kind of configuration that needs to be
performed to get ruby to open it as a directory and load all the
files?  Could there be an error in the gem spec file?

Simple gems like blinkenlights and creditcard work as expected but
they have single targets like lib/blinkenlights.rb and
lib/creditcard.rb.
 
Also, with require_gem instead of require this is the error report:
/usr/lib/ruby/site_ruby/1.8/rubygems.rb:251:in `report_activate_error': Could not find RubyGem fox14 (>= 0.0.0) (Gem::LoadError)
        from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:188:in `activate'
        from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:66:in `active_gem_with_options'
        from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:59:in `require_gem'
        from zeg.rb:2
