I'm working on setting up ejabberd with the native Mysql backend. I checked out the current development copy from Subversion today (4/03/06).
I wanted to run the ejabberdctl-extra patch from contributions but unfortunately the patch fails:
[root@dns1 src]# patch < /usr/local/download/ejabberd/ejabberdctl-extra.diff

ejabberdctl-extra is deprecated, try mod_ctlextra
ejabberd SVN includes improved ejabberd_ctl support. I've moved the code from the patch to an independent module: mod_ctlextra.
Try it and tell me if everything works.
