Open Stack

Greetings!

I am sending this email because I have some problems with starting the devstack.

I cloned the devstack repository in my laptop and ran ./stack.sh in the devstack directory.
But the konsole complains about that and some of the error messages are shown below.
        + screen -S stack -p g-api -X stuff '/usr/local/bin/glance-api --config-file=/etc/glance/glance-api.conf & echo $! >/opt/stack/status/stack/g-api.pid; fg || echo "g-api failed to start" | tee "/opt/stack/s'atus/stack/g-api.failure"
        + echo 'Waiting for g-api (160.85.231.43:9292) to start...'

I can not find any helpful materials on this over the Internet.
Could anyone of you help me fix this?
I would really appreciate your help
