Ruby on Rails

Hi, not sure if I got it well:
so you do have Ruby1.9, Gem1.3.7 but only Rails version 2.3.5, now you
want to update, right? On Ubuntu try this:
"gem update rails"
If you have permission problems then "sudo gem update rails" except if
you have RVM installed, then don't use sudo when installing gem.
Then make a cleanup "gem cleanup"
Troubleshhot: "rails -v" should be 3<

Someone told me he only could solve his Zlib problem with RVM, because
it has a package for it:
http://rvm.beginrescueend.com/packages/zlib/
I really recommend to use RVM, because you can prevent later problems
also.
Let me know if you have further problems, good luck,
Zoli
