Hmmm. Interesting. What OS and php version please.

BTW php artisan and L5 welcome work fine

[GrahamCampbell]

Try running "which phpunit".

[neomerx]

installed globally

/home/user/.composer/vendor/bin/phpunit

[GrahamCampbell]

That's probably the issue then. What's "phpunit --version".

[neomerx]

$ phpunit --version
PHPUnit 4.1.6 by Sebastian Bergmann.

[GrahamCampbell]

Upgrade to 4.4.

[neomerx]

$ phpunit --version
PHPUnit 4.5.0 by Sebastian Bergmann and contributors.

reproduce steps 1-3

$ phpunit 
PHP Fatal error:  Cannot redeclare class PhpParser\Autoloader in /home/user/folder/laravel/vendor/nikic/php-parser/lib/PhpParser/Autoloader.php on line 9

PHP  13. require() /home/user/folder/laravel/vendor/nikic/php-parser/lib/bootstrap.php:3

But
It works fine if

$ php vendor/phpunit/phpunit/phpunit
$ php vendor/phpunit/phpunit/phpunit --version
PHPUnit 4.5.0 by Sebastian Bergmann and contributors.

Yeh, looks like we don't support global phpunit installs. Take this issue up with phpunit - it looks like a bug on their end.
