How about a chapter on how to *uninstall* Ruby and Rails? Here's how you 
do it on a Gentoo Linux system:

# emerge --unmerge ruby rails
# emerge -uvDN world
# emerge --depclean

If you have packages that depend on Ruby, the second line will 
re-install it. And the third line will delete any orphaned packages.
