[TYPO3-50-general] problem create a package on mac

[Federico Bernardin]

Hi,
I'm testing FLOW3 with an example similar to Blog (my package is  
Project).
I create all necessary files and folder like in getting started, but  
when I create Repository object (exactly like Blog example, infact I  
renamed word Blog into Project), FLOW3 answer:

#1166550023: Object "F3\Project\Domain\Repository 
\ProjectRepository_AOPProxy_Development" is not registered. (More  
information)

F3\FLOW3\Object\Exception\UnknownObject thrown in file
/Users/federico/Sites/FLOW3-PDT/local-flow3/Packages/Framework/FLOW3/ 
Classes/Object/Manager.php in line 314.

Then when I remove package Project and clear cache, error remains.

I use macport on Snow Leopard, and I don't succeed to test FLOW3. It'  
very frustrating.

Can you help me?

Thanks
Federico
