Comment:
This ''did'' install normally on 4.7.1.alpha1 on Mac OS X 10.6. So
perhaps it's just certain Linuces that don't work.
----
On a related note, there seems to be exactly one set of doctests which
even require this package optionally. I'm surprised that
numerical/backends/ and the graph stuff doesn't. I'm cc:ing Nathann about
this. After all, hopefully optional tests are at least ''sometimes'' run
for major releases...
And when I run them, I get
{{{
sage -t -optional "devel/sage/sage/combinat/integer_vector.py"
**********************************************************************
File "/Users/karl-
dietercrisman/Downloads/sage-4.7.1.alpha1/devel/sage/sage/combinat/integer_vector.py",
line 279:
sage: print gale_ryser_theorem(p1, p2, algorithm="gale") # Optional -
requires GLPK or CBC
Expected:
[1 0 1 1 0]
[1 0 1 0 1]
[1 1 0 0 0]
[0 1 0 0 0]
Got:
[0 0 1 1 1]
[1 1 1 0 0]
[1 1 0 0 0]
[1 0 0 0 0]
}}}
And all the ones with 'generic backend' fail as well... Nathann?
