I was able to install doctrine domains through the command line as part of the symfony blog tutorial.
tutorial for symblog part4
However im now get the class could not be found error?
Fatal error: Class 'Doctrine\Bundle\DoctrineMigrationsBundle\DoctrineMigrationsBundle' not found in /media/sf_projects/symBlog/app/AppKernel.php on line 24
