Subject: require 'green_shoes' -> ruby: no such file to load -- green_shoes (LoadError)

Sorry for this newbie's question, but I'm stuck:

I installed the "green_shoes" gem on my Win7 PC (together with Ruby
1.8.7
that is) and everything looks fine at 1st glance: A "gem list" on the
cmd line results in this:

*** LOCAL GEMS ***

atk (1.0.0 x86-mingw32)
cairo (1.10.0 x86-mingw32)
columnize (0.3.4)
gdk_pixbuf2 (1.0.0 x86-mingw32)
glib2 (1.0.0 x86-mingw32)
green_shoes (0.255.0)
gtk2 (1.0.0 x86-mingw32)
linecache (0.46)
pango (1.0.0 x86-mingw32)
pkg-config (1.1.2)
rake (0.9.2)
rbx-require-relative (0.0.5)
ruby-debug (0.10.4)
ruby-debug-base (0.10.5.jb2 mswin32, 0.10.4)
ruby-debug-ide (0.4.17.beta5)
rubygems-update (1.8.7)

Now if I try to run a "hello world" like...

require 'green_shoes'
Shoes.app( :width => 250, :height => 250 ) do
  para 'Hello, world!'
end

(stored in c:\temp\testshoe.rb )

...RM tells me that it can't locate the gem:

c:\temp>irb -rgreen_shoes testshoe.rb
C:/Ruby187/lib/ruby/1.8/irb/init.rb:254:in `require': no such file to
load -- green_shoes (LoadError)
        from C:/Ruby187/lib/ruby/1.8/irb/init.rb:254:in `load_modules'
        from C:/Ruby187/lib/ruby/1.8/irb/init.rb:252:in `each'
        from C:/Ruby187/lib/ruby/1.8/irb/init.rb:252:in `load_modules'
        from C:/Ruby187/lib/ruby/1.8/irb/init.rb:21:in `setup'
        from C:/Ruby187/lib/ruby/1.8/irb.rb:54:in `start'
        from C:/Ruby187/bin/irb:13

Now the system DOES tell me that green_shoes is known, however:

c:\temp>gem which green_shoes
C:/Ruby187/lib/ruby/gems/1.8/gems/green_shoes-0.255.0/lib/green_shoes.rb

So I tried to hint it to the correct path:

c:\temp>set LOADPATH
loadpath=C:/Ruby187/lib/ruby/gems/1.8/gems/green_shoes-0.255.0/lib/

..but still to no avail. So what am I doing wrong??

Many thanks!
