I make rpm from git repo today, when I ran engine-setup, I got answer like this:
Internal Error: Can't encrypt database password

And here's the log file:

2013-05-09 13:56:25::ERROR::engine-setup::2528::root:: Traceback (most recent call last):

File "/usr/share/ovirt-engine/scripts/common_utils.py", line 499, in execCmd
    raise Exception(msg)
Exception: Internal Error: Can't encrypt database password

What's the problme?
