Rodolfo can you take a look at this and/or pull the SCL guys who did the 2.7 image in?

thanks

when excute the commands :
sti build  https://github.com/openshift/django-ex.git  openshift/python-27-centos7 my-python-image 
or 
sti build  https://github.com/openshift/django-ex.git  openshift/python-27-rhel7 my-python-image

I've seen this before, and it is a benign message caused by an old version of PIP.

The fix would be upgrading pip, which is not feasible unless we have newer packages and we're not using them... IIRC we use pip 1.5.6, release on May 17, 2014. The next version which fixes this problem is 6.0, released on Dec 22, 2014.

There are many GitHub issues in the gunicorn project mentioning this "bug":

wewang, since this is pending a fix in upstream pip being available in RHEL package of 'pip', I'm moving this bug to SCL team to deal with it.

There is nothing we can do about this right now. Please feel free to re-open this after the SCL team bump the version and you will still see this error.
