[FLOW3-general] FLOW3 from Git and Blog package

[Fernando Arconada]

Hi

How should I install Blog Package inside a fresh FLOW3 git clone. I'm 
continuously having exceptions whith FLOW3 at the beggining with Welcome 
package and now with the Blog one: Uncaught Exception in FLOW3 Column 
name `flow3_persistence_identifier` referenced for relation from F3\Blog
\Domain\Model\Comment towards F3\Blog\Domain\Model\Post does not exist. 
thrown in file Packages/Framework/FLOW3/Resources/PHP/Doctrine/ORM/Tools/
SchemaTool.php in line 485 


Really frustrating, with alpha14 all seems to work but alpha14 doesnt 
have Doctrine

Help please

Kind Regards

Fernando
