"testing" Error

I get the following when my environment is set to "testing":

Code:

Warning: Use of undefined constant SUPPORTPATH - assumed 'SUPPORTPATH' (this will throw an Error in a future version of PHP) in /opt/lampp/htdocs/system/Config/AutoloadConfig.php on line 96

Warning: Use of undefined constant SUPPORTPATH - assumed 'SUPPORTPATH' (this will throw an Error in a future version of PHP) in /opt/lampp/htdocs/system/Config/AutoloadConfig.php on line 192

Warning: Use of undefined constant SUPPORTPATH - assumed 'SUPPORTPATH' (this will throw an Error in a future version of PHP) in /opt/lampp/htdocs/system/Config/AutoloadConfig.php on line 193

I'm using beta 1. Where is SUPPORTPATH supposed to be defined?

Good news is everything seems to work fine in development mode.

Simpler is always better
