I have a laptop running Gentoo. A Compaq V2000 —a model I’d highly recommend—Dothan chip and all that. One of the reasons I chose Gentoo was because of the simplicity of upgrading software I use from CVS. Keeping multiple versions of Ruby on the same machine is really sly as well.

 # emerge ruby
 # emerge ruby-cvs

Use ruby18 or irb18 to explicitly use 1.8. Or ruby19 and irb19 to explicitly use 1.9. And then Gentoo has a use.perl-style script to alter the symlinks of ruby or irb itself.

 # ruby-config ruby18
 # ruby-config ruby19

I’d really like to know how this works (does it?) on Debian or Slackware.
