When running phpspec I see:
$ phpspec MySpec.php
PHP Fatal error: Class '\PHPSpec\Runner\Example' not found in /usr/share/php/PHPSpec/Runner/Collection.php on line 163
$

OS: Ubuntu 9.10
PHP: 5.3.2

This happens after applying the fix in [gh-6] and is a similar issue in another place and can be probably be solved with a similar strategy.
