A little while ago I installed openerp for my company. I'm in the process of moving the installation to another server. In the new server however a large number of modules aren't showing up.

There's about 200 modules I have the option to install on the old server, but only 23 on the new installation. Some of the ones I know for sure are missing are the bcrypt module, database anonymization , powermail, knowledgebase. As far as I can tell I have configured it the same, the addons directory on both is nearly identical and I can see the files for crypt, knowledge, anonymization.

Any ideas?
