First time Ruby Install

ruby-talk

Hey, this is my first time ever working with Ruby so this makes me a
total n00b.

Here is the error I received:

bash-3.2$ sudo gem install rails
Building native extensions. This could take a while...
ERROR: Error installing rails:
  ERROR: Failed to build gem native extension.

Here is the result logged:

Im assuming OSX Lion is missing something? Should I do an update?

do this:
bash < <(curl -s https://rvm.beginrescueend.com/install/rvm\)
add
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

to your ~/.bashrc file (at the end) if it didn't do this for you already.
the rvm instructions tell you this.

open a new shell.
rvm install 1.9.2 (let it do its thing)
rvm 1.9.2
gem install bundler rails
rails new project_name_here

#enjoy your rails experience.
I know this is a lot of over head, but it gives you a lot of benefits.
name you can run multiple ruby interpreters, gems are a lot easier to deal with.
You aren't beholden to apple for ruby support.. it's what all the cool kids use.

you'll want to learn about gemsets and etc, but this will get you
going in a good direction.
