How to set GCC as default compiler in Yosemite?

Question

GCC

Compiling v8 for x64
Using python 2.7.6
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Unable to find a compiler officially supported by v8.
It is recommended to use GCC v4.4 or higher
Using compiler: g++
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Unable to find a compiler officially supported by v8.
It is recommended to use GCC v4.4 or higher

When installing gems, such an error appears. I so understood that it is necessary to change the compiler. The question is how to do it? Googling has not yielded results, everything is still the same. Please help.
