Uninstall Ruby / PHP in existing Mac OS

Hi Guys, posting this after a long period as was little busy ;-). Anyways lets get into the subject.

Whenever OSX 10.x version installed, by default PHP / Ruby will also be installed. This is good but sometimes we don't want the particular version installed so to remove this we need to do the following steps.

For Ruby

sudo mv /System/Library/Frameworks/Ruby.framework/Versions/1.8 /System/Library/Frameworks/Ruby.framework/Versions/1.8.dead

sudo mv /usr/bin/ruby /usr/bin/old_ruby

sudo mv /usr/bin/gem /usr/bin/old_gem

For PHP

sudo mv /usr/bin/php /usr/bin/old_php
