Had some minutes to spend today and thought it would be pretty neat to have
YARV (as announced on http://redhanded.hobix.com/cult/yarvMergedMatz.html) on
ArchLinux, so i went ahead and created a little PKGBUILD 
one can find it at AUR (ruby-yarv-svn):
http://aur.archlinux.org/packages.php?do_Details=1&ID=4191
installation as usual (aurbuild, qpkg or makepkg yourself)
Not sure if this belongs to ruby-talk, but for all the ruby-addicted archers
out there this is pretty good news
after installation one can use it with ruby_yarv - there are issues with
rubygems as everybody might expect, so calm down a bit - your favorite gems
won't run on it (yet).
And it's also a little reminder for all the other maintainers out there, build
some packages for YARV, people want to try it and there is no reason why they
shouldn't be able to do it 
Not to mention that it would be pretty good advertisement for ruby to have
something to show off, right?
