Periodic job periodic-mistral-python27-mos70 fails:

The reason is pecan==0.6.1 that was used during the test. That version was used because it's available through system packages. pecan==0.9.0 fixes the problem [3].

Although latest periodic jobs are green, the problem is still there. The reason is that pecan==1.0.0 is used, because of some component that have such requirement, and it forces pip to ignore pecan==0.6.1 from constraints.
