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 Fetching gem metadata from https://rubygems.org/..........

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: ``` Installing json (1.8.1) Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /Applications/rubystack-1.9.3-19/ruby/bin/ruby extconf.rb creating Makefile make compiling generator.c sh: line 1: 67709 Trace/BPT trap: 5 /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk / -find as 2> /dev/null as: error: unable to find utility "as", not a developer tool or in PATH make: *** [generator.o] Error 2 Gem files will remain installed in /Applications/rubystack-1.9.3-19/ruby/lib/ruby/gems/1.9.1/gems/json-1.8.1 for inspection.
