[ruby-gnome2-devel-en] rake gem:install fails on wrong dependency order

[Detlef W. <det...@gm...>]

Hi,

if I try to install a fresh checked out git/master with rake it fails on
rake gem:install
with the following message

This is because in the top level Rakefile pango should be build before 
cairo-gobject is build. But pango has cairo-gobject as it's dependency.
