cd /tmp

Then it fails to compile with with this error - http://pastebin.com/6KRdjPPH
What do I do?
Hello, northernarcher!
You need to install readline. Did ./configure kick out any warnings? I believe it would've caught this. You'll likely also need libssl, build-essential, and a half-dozen other packages. If you're building Ruby in order to build a Rails project, these are the packages you'll need installed before you get started:
build-essential
openssl
libreadline6
libreadline6-dev
curl
git-core
zlib1g
zlib1g-dev
libssl-dev
libyaml-dev
libsqlite3-dev
sqlite3
libxml2-dev
libxslt-dev
autoconf
libc6-dev
ncurses-dev
automake
libtool
bison
nodejs
subversion
For what it's worth, you might want to try using chruby (https://github.com/postmodern/chruby) and ruby-install (https://github.com/postmodern/ruby-install) as it will isolate your ruby versions and handle dependency installation for you. Keeping Ruby up to date is a bit of a chore and these two utilities will help.
There are other build automation tools and version managers but these have worked the best for me. They're lightweight and don't do any of the silly tricks some of the other packages do.
One last thing: Ruby 2.0.0 is severely out of date. The current stable release is 2.3.0 as seen on ruby-lang.org.
Good luck and Happy Hacking!
Okay, so I tried the ruby-install program and it says it installed successfully but the system can't see it and it does not show up in the package manager.

When you install software in this way you're going behind the package manager's back so it's not going to know about it.
Alright, well can I live without that bit working. How can I make it so the system can use it though?

If you really want Ruby 2.0, why not simply installing the package named "ruby2.0" in Trisquel's repository?
The reason is that basically it's not really what it says it is. If you install the ruby2.0 package what you actually get is ruby1.9.3 for some reason. A real 2.0 Ruby is not actually in the repo. I don't know if this is a bug or just a mislabeling but I reported it, and the workaround I was given is what I am trying to do now.
