When you run symfony command, you are actually executing /usr/local/bin/symfony. This is a symlink to the symfony command in a specific version of symfony from our repository. To change the version, follow these steps:
- delete the current symlink by executing: rm /usr/local/bin/symfony
- create a new symlink (replace the symfony version you want in the path): ln -s /usr/local/php/symfony-1.4.1/data/bin/symfony /usr/local/bin/
