Error message when I start keystone. I fear I have seriously broken python, (because I had keystone working at one point...) but can't find any clues about 'module' or 'load-backends'. Any suggestions on where to start looking for more info about this problem???

from keystone-startup.log

smafulli, you asked for it...

I am installing based on the 3-node design from docs.openstack.org/icehouse.

On the controller node I installed keystone first, and it was working because I could make the keystone users, services, roles, endpoints, etc...

I then proceeded with image, compute & was working on networking all on the controller node when I started having problems and realized keystone was not working anymore.

When installing glance, I had to rebuild pycrypto with a different gmp. But after that I was still able to create the glance user in keystone and register services and endpoints, etc...

Then I moved on to nova on the control node. yum installed stuff, had some problems with syncing the nova database, but got that resolved. Created nova user in keystone, registered it and service, endpoints, etc... Started noticing the nova-api errors with keystonemiddleware.auth_token. got that resolved.

Moved on to installing/configuring nova on my compute node. No problems noticed.

Moved on to installing neutron on network controller node. Yum installed packages, made database in mysql, added keystone user & service, etc... in keystone. started setting up neutron on network node, installed pkgs, configured neutron.conf, created bridge, messed around with network interfaces and addresses.

Now keystone won't start. Does not make sense. We have had to re-downloaded /usr/lib/python2.6/site_packages/keystone to fix some other python errors. But this one, we can't find anymore info...
