how to create custom zenpacks on zenoss5 beta 2

Hi Zenoss team,
how to create custom zenpacks on zenoss5 beta 2

1) tried as suggested in the documentation:
sudo serviced service run zope zenpack install ZenPack-File-Name
This fails with a traceback. See other thread I posted yesterday on this.

2) from the GUI there is no install zenpack as in previous release (probably still in development)

3) Created a new container that builds over zenoss/core-testing, with my .egg file from previous release
in /opt/zenoss/ZenPacks directory. Also updated easy_install.pth to include this ZenPack.
This does not even show up in the GUI.

-- so created another zenpack with the same name, that was already present in the ZenPacks directory,
zenpack GUI comes up with no options for the zenpack to be set.

-- Probably zenoss is upset because of my .egg file with same name already present.
But if so, why it did it not acknowledge that such a zenpack was present and cannot be loaded for whatever reason.

4) Created a new zenpack.
restarted serviced to check whether zenpack is persistent.
Again, after all services are up, zenpack is reported as below
" This pack was just installed, or is missing or broken. Please restart Zope. "

Now, I do not know how to test zenoss 5 beta 2 with any custom zenpacks other than what is bundled with the zenoss.
Can anyone please help, how to create/install a custom zenpack.
Did anyone else have success If so what did you do to get this working, what is your dev environment like.

Your inputs/help will be much appreciated.
Thanks,
LN
