I am trying to create my first application on ruby rails.
All steps until creating my own project work ---- see here
In the ruby console I type:
sudo rails new helloworld
.. then it does some creational stuff till it hits the following lines:
run bundle install

Outside rubyconsole it works. However, that does not solve the issue above.
I followed these steps:
How to use/install gcc on Mac OS X 10.8 / Xcode 4.4
I also followed the steps here:
http://new-bamboo.co.uk/blog/2013/10/24/3-quick-tips-for-coding-with-os-x-10-9-mavericks
Any help would be much appreciated .. Thanks, George
UPDATE: I run the following:
cd /usr/bin
sudo mv gcc gcc_mavs
sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 gcc
Now I get a different error message:

Ok, completely removed xcode & developer tools.
Reinstalled xocode 5.02 & developer tools for maverick (late october)
run the following command:
sudo xcode-select -switch /Library/Developer/CommandLineTools
