Comment(by was):

 {{{
 I can make the problem described in sage trac ticket #6825
 reproducible and not intermitent.

 If you remove

     local/lib/python/site-packages/scipy/stats/mstats_basic.pyc

 then you will see the error when you run

     sage -t  "devel/sage/sage/modules/vector_real_double_dense.pyx"

 This reproduces the problem whether or not you move the build directory.


 One possible fix for the problem is to remove line 106 of

     local/lib/python/site-packages/scipy/stats/mstats_basic.py

 which is the assert line about which the output message complains.


 I do not know a lot about python, but it seems that
 python evidently has some check that the sage tree has moved and
 so rebuilds *.pyc files if they have not been regenerated recently.
 I am surprised that local/bin/sage-location does not remove all the
 *.pyc files and rebuild them when the sage tree moves.
