I have recently updated my OS X to 10.10 and since then facing issue installing ruby through RVM. There is a dependency on gcc46 which I am unable to resolve. Any help is appreciated. Below is the error stack.
rvm reinstall ruby-1.9.3-p547
ruby-1.9.3-p547 - #removing src/ruby-1.9.3-p547 - please wait
ruby-1.9.3-p547 - #removing rubies/ruby-1.9.3-p547 - please wait
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.10/x86_64/ruby-1.9.3-p547.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

brew install gcc46
==> Installing gcc46 from homebrew/homebrew-versions
gcc46: OS X Mavericks or older is required for stable.
Use `brew install devel or --HEAD` for newer.
Error: An unsatisfied requirement failed this build.
EDIT :
I was able to install using below command.
rvm install 1.9.3 --with-gcc=clang
Could someone help me understand what's the difference with the above command? Thanks
Thanks @JanStrnádek for the answer. I solved all the dependencies from left to right and installed gcc using the below command and tried installing ruby again. It worked.
brew install homebrew/versions/gcc48
Always try to use the latest version whenever possible, or else check the correct versions of each component which is compatible with the version of the component you are installing.
If you follow this guide it will be much easier.
I am completely new to ruby, but it worked fine for me by using this.
