Ruby Rails - issue with gcc on mac

I am trying to create my first application on ruby rails.

  • I am on Mac OsX (Mavericks)
  • I have the latest xCode installed (5 i believe) + command line tools
  • I have installed the bitnami bundle ruby stack
  • I have added rails (sudo gem install rails -V)

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

Sovled.
