I just tried to start my DevStack and again, I had issues with a "builtin" 
olso module: "import oslo.config" doesn't work, whereas olso.config was 
installed (system wide) by pip.

"pip list|grep olso" told me that oslo.config, oslo.messaging, oslo.rootwrap 
and oslo.vmware are installed.

My workaround is to uninstall all olso modules:
sudo pip uninstall oslo.config oslo.messaging oslo.rootwrap oslo.vmware

./stack.sh reinstalls them and now it works.

Current state:

oslo.config (1.3.0a0.40.gb347519)
oslo.messaging (1.3.0.8.gc0c8557)
oslo.rootwrap (1.2.0)
oslo.vmware (0.3.1.g49097c0)

I never understood how these .pth files work.
