Error when installing ruby with rvm

I am trying to install ruby in MacOS

In file included from :0:0:

.ext/include/x86_64-darwin14.0.0/ruby/config.h:77:16: error: duplicate

I set env CPP=/usr/bin/cpp

Thanks for your help.

I fixed it by following this link: https://gist.github.com/zenkay/3237860

Mountain Lion supports only XCode 4.4 or greater. Basic 4.4 installer doesn't install Unix's standard command line tools by default. You have to install it using separate package (from Apple Developer's) or directly from XCode 4.4 preference panel (Preferences : Downloads : Components : Install).

When installation is complete, tools are finally available but is not enough. Unfortunately llvm_gcc-4.2 compiler ship with XCode is not suitable to compile Ruby (it works but some features are buggy).

You have to install the stand-alone gcc package.

Basically, i have to install another version of gcc instead of using the one with Xcode.
