I saw you tried on Ruby 1.9 If you are new, I think the best is the default, easiest way. First try it from Synaptic, and with the latest stable versions, but as you wish.
I had plenty of problems installing Rails on Ubuntu, so if you still cannot install it well, please let me know, or also you can find me in private.
than try:
*sudo** gem install rails*
+your password

hey gezope! I could solve my problem!
my mistake was don't make a "clean compilation" after install the zlib
library.
So thanks for your quick answer anyway, I'm on rails now
Hey guys, I'm having this same zlib problem on gems. See my output below
for what I have installed, and the error I get when I try and run any
gem commands. Also as you can see I have zlib[devel] installed. Some one
mentioned something about the headers being installed with zlib??? I'm
not sure I know what that means...could someone enlighten me? Any help
appreciated...thanx!

...hey Colin, thanx for the reply. Yes, I have zlib and zlib-devl
installed.
Yes, I knew that. I was making the point that on Ubuntu it is zlib1
and zlib1g-dev in case it is relevant. I realise that it may not be
relevant on your OS.
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
...hey Z, thanx for the reply. 'gem cleanup' does work, but when I try
'gem install rails' I get the zlib error below. I can't seem to install
any gems due to the zlib problem. I looked into rvm, but I can't see to
get that installed. I am using Fedora, so I used yum to install rvm, but
can't seem to get that working either. rvm doesn't seem to be in my
path, and I can find an executable for it in the .rvm folder. I'm going
to continue working on this, and will post back when I finally figure it
out. Thanx!

Did you make the changes to .bashrc (or whatever the equivalent in
Fedora) as described on the website after installing rvm? Until you
do that rvm is not available.
I did make the changes in .bashrc, I think maybe those instructions are
not applicable to fedora. For instance after installing I don't have a
/usr/local/rvm folder.

Hey Colin...thanx so much..that worked! Its a little unsatisfiying
through, because I'm not sure exactly what part of that tutorial fixed
the gem install. At any rate thanx so much for the link.
