+	The default version of Ruby is now 1.8 on all platforms
+	including the i386.
+
+	Users on the i386 platform need to follow the below
+	instructions to cope with this upgrade.
+
+	If you are a ruby developer and want to keep ruby 1.6 as
+	default, please add RUBY_DEFAULT_VER=1.6 to /etc/make.conf.
+
+	Otherwise, please run the following series of commands to
+	migrate to ruby 1.8:
+
+	1) Reinstall portupgrade manually (and as a result ruby 1.8
+	   will be installed):
+
+	   $ pkg_delete portupgrade-\*
+	   $ (cd /usr/ports/sysutils/portupgrade; make install clean)
+
+	2) Reinstall everything that depends on ruby 1.6 to use ruby
+	   1.8 instead:
+
+	   $ portupgrade -fr lang/ruby16
+
+	3) Reinstall ruby 1.8 (because the previous step kills
+	   symlinks)
+
+	   $ portupgrade -f lang/ruby18
+
+	4) Deinstall ruby 1.6 stuff (if you are paranoia)
+
+	   $ pkg_deinstall -ri lang/ruby16
+
+	5) If the above commands do now work somehow and portupgrade
+	starts causing LoadError, please reinstall portupgrade
+	manually again.  Whenever you get confused, you can just
+	deinstall portupgrade and all the ruby stuff (run "pkg_delete
+	-r ruby-\*") and reinstall portupgrade as a last resort.
+
+	Next time ruby is major upgraded, you won't need to do this
+	kind of messy work because some subtle changes have been made
+	to the ruby port infrastructure to make it easier to handle
+	multiple versions of ruby.

 	Mozilla will now default to using GTK2, and will only compile
 	against Gtk+-1.2 if explicitly requested.  This is in exact
