Now this is a lifesaver...

sudo pear install -a phpunit/PHPUnit-3.5.14
Duplicate package channel://pear.phpunit.de/File_Iterator-1.3.3 found
Duplicate package channel://pear.phpunit.de/File_Iterator-1.3.2 found
install failed

Any help?

sudo pear install -a phpunit/PHPUnit-3.5.14

Duplicate package channel://pear.symfony-project.com/YAML-1.0.6 found
Duplicate package channel://pear.symfony-project.com/YAML-1.0.2 found

Any suggestions..?
