I'm new to Ruby on Rails, and I'm getting the below error when I'm installing it.
Please note, I have installed the latest Xcode and installed command line tools, and I'm using OSX 10.8.4. I've installed Ruby 2.0.0 as well.
-bash-3.2$ sudo gem install rails

I had similar problem and it gets solved by installing command line tools:
xcode-select --install
The symlinking did not solve the problem for me. I uninstalled my ruby that I previously had installed using rvm by typing rvm uninstall ruby-2.0.0
and then I typed rvm requirements
. This command found that I needed a few other things, such as gcc46. It's strange that the gcc compiler was needed, even though I had installed the xcode command line tools, and gcc was most definitely installed on my system.
So, if none of the usual methods are working, give rvm requirements
a shot!
