Postinstall on MacOS never starts the server

After installing on MacOS, the preference panel isn't available, so I have to resort to setting up the server manually.

bin/start doesn't actually start it, and bin/postinstall.sh does this:

shard:/Applications/ejabberd-1.1.1 trejkaz$ sudo bin/postinstall.sh 

       -=- ejabberd post installation script -=- 
              (c) 2005-2006 Process-one 

* Checking ejabberd installation

* Starting ejabberd "default" instance
thread_get_state: Unknown error: 0
.thread_get_state: Unknown error: 0
.thread_get_state: Unknown error: 0

I get the same error trying to run bin/ejabberdctl.

I suspect that something is seriously wrong with the MacOS version of Erlang.
