Packaging of ruby 1.9.1 in progress, but if you cannot wait and want to test new features you can build the package yourself:

Installing build-dependencies:

 sudo aptitude install debhelper cdbs dpatch \ 
 patch autoconf m4 bison binutils libgdbm-dev \ 
 libncurses5-dev libreadline5-dev tcl8.4-dev \ 
 tk8.4-dev zlib1g-dev libssl-dev procps

Building the package:

 sudo atitude install devscripts build-essential
 mkdir /tmp/ruby191 && cd /tmp/ruby191
 dget https://launchpad.net/ubuntu/karmic/+source/ruby1.9.1/1.9.1.243-0ubuntu1/+files/ruby1.9.1_1.9.1.243-0ubuntu1.dsc
 dpkg-source -x ruby1.9.1_1.9.1.243-0ubuntu1.dsc
 cd ruby1.9.1-1.9.1.243 && debuild
 cd .. && sudo dpkg -i *.deb

And finally You can get it from Ubuntu on Rails PPA:

 sudo aptitude install ruby1.9.1 ri1.9.1 rdoc1.9.1 ...

and much more… :)
