Comment:
As noted in #10739, I have two independent builds of sage-4.6.2.alpha3 on
my machine, one in which this test passes and the other in which it fails.
Replying to [http://trac.sagemath.org/sage_trac/ticket/10739#comment:10

> But if one build repeatedly passes "make ptest" and the other
consistently fails, this would be an excellent opportunity to debug #9310.
Presumably the only difference is that the first compilation was
interrupted at one point, so the order in which spkgs were built is
different.
Precisely, the first build was interrupted (see #10739 for details) and
the second was not.
> This might have changed linked libraries in some components due to
(undiscovered) soft dependencies, for example. Can you diff the two trees
(excluding log files etc) and find out the difference?
I ran {{{diff -rq}}} on the two directories and there are about 25000
files that differ (pyc files, pyo files, ...). I figured that this might
have something to do with hardcoded paths, so I moved one out of the way,
moved the other into its place, launched sage to reset the hardcoded
paths, and then ran {{{diff -rq}}} on the two trees. It still shows about
25000 differing files.
Any suggestions on what to try next?
