My ultimate goal is to install the current version of Ruby on Rails. I am running on OS X Mountain Lion. Here's my process so far:
Installed RVM
$ \curl -L https://get.rvm.io | bash -s stable
Checked for known (and I assume approved) installs
$ rvm list known
I see that the current stable build is available
[ruby-]2.0.0[-p247]
Key in command to install
$ rvm install 2.0.0-p247
Note: I also tried these install commands
$ rvm install ruby-2.0.0-p247
$ rvm install ruby=2.0.0-p247
I'm getting nowhere fast. Results:
$ rvm install 2.0.0-p247
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.8/x86_64/ruby-2.0.0-p247.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Installing requirements for osx, might require sudo password.
Certificates in '/usr/local/etc/openssl/cert.pem' already are up to date.
Requirements installation successful.

There has been an error while running configure. Halting the installation.
I also ran this command in debug mode. To avoid clutter, you can access it here.
Also, here is the log:

This is my first installation via RVM. $rvm list returns no gems.
Please ask if any additional information might be helpful.
Edit - HERE is the log in case that might help anyone.
Something must have been wrong with either my Xcode or my Command Line Tools install. Reinstalling both made everything run beautifully.
