It looks that there is a release conflict on Arch Linux. Though I am not
sure that this will help you, try running the following two commands:

 ruby1.8 -e 'require "gtk2"'
 ruby1.9 -e 'require "gtk2"'

Using ruby1.8, ruby1.9, irb1.8 or irb1.9 rather than just ruby or irb
forces the selected ruby version you wish to run. If this solves your
problem we can fix your ruby and irb to use the correct version.

I also suggest you post your problem on "Ruby-Gnome 2" forum
(http://www.ruby-forum.com/forum/12), where Gtk problems are discussed.

Good luck,
Torli

What does your 'get' script/alias look like? Are you sure your package
caches are up to date? Try

$ pacman -Syy pango ruby-pango ruby-gtk

also check

$ strings /usr/lib/ruby/site_ruby/1.8/i686-linux/pango.so | grep
pango_glyph_item_get_type

and

$ strings /usr/lib/libpango-1.0.so | grep pango_glyph_item_get_type

they should both return 'pango_glyph_item_get_type'

on my system i have
ruby-gtk2 0.18.1-1
ruby-pango 0.18.1-1
pango 1.22.4-1

If all else fails, try a different mirror, try to rebuild pango,
ruby-pango. ruby-gtk2 using current PKGBUILDS, file a bug report...
