problem installing ejabberd on mac osx 10.6.7/8

Hi,

I am having a problem installing ejabberd on a macbook pro intel core i5 using the binary installers such as http://www.process-one.net/downloads/ejabberd/2.1.8/ejabberd-2.1.8-mac-i... i have tried ejabberd 2.0.3,2.1.2,2.1.8 and all fail to run the post installation script, the ejabberd process is running but the admin console is not available and i cant get any xmpp connections, here are the error messages from 2.1.8 version:

i have tried it on both osx 10.6.7 and 10.6.8 and still the same problem.

Does anyone know what the above error messages mean and how i can fix it?

Thanks,
Conor
