gcc-4.6 Error with installing ruby gem scrypt

Question

I am trying to install scrypt gem and kept on running errors as following.

I have tried to reinstall ruby, reset rvm and also reinstall the gcc but non of these helped. Please let me know if there is a way to solve this. The following is the environment:

ruby -v 
ruby 1.9.3p551 (2014-11-13 revision 48407) [x86_64-darwin13.4.0]

rvm -v 
rvm 1.26.6 (latest) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

Besides that, I would like to know if there is material that I can study for setting up the environment in general for example: what does each line in the .bashrc file mean?

Thanks in advance.

Does this help? http://stackoverflow.com/questions/4391192/why-do-i-get-cc1plus-error-unrecognized-command-line-option-arch — fvu, Dec 26 '14 at 20:40
@fvu Hi, I have installed the command line tool but still got the issue. — Cheng Lun Chen, Dec 26 '14 at 21:02
You may want to try eliminating RVM from the mix, by trying `ruby-install`. — joelparkerhenderson, Dec 26 '14 at 21:40

Try these steps in CLI

brew tap homebrew/versions && brew install apple-gcc42

brew link --force apple-gcc42

ln -nsf $(which gcc-4.2) /usr/bin/gcc-4.2

After that try to install your gem.
