At first I thought it was a brilliant idea, so I did it but gem1.9
install bombed because it did not find gem, I do not think that I did
anything stupid.

Anyway I have opted for ruby1.9 into /usr/local/bin and jruby in my
home dir with an alias to $JRUBY_HOME/bin/jruby
and shell functions for jgem, jrake, jirb etc.

That is painless and good enough for me.

BTW I spent a day of installing and reinstalling ruby1.9 and ruby1.8
on the same machine and nothing I tried made them coexist without
*major* shell scripts for switching. As those might not scale to
changes I gave up on it, but maybe I was too tired and missed
something stupid.

Cheers
