On Intel Mac OS X.5: after jumping through all of the appropriate
hoops to make this version, sage -testall -long had four failures, two
of which are familiar:
1. #3758 sage -t -long devel/sage/sage/crypto/mq/sr.py
2. #3760 sage -t -long devel/sage/sage/schemes/elliptic_curves/
ell_finite_field.py
Two were new to me:
3. numerical noise (in which some dots ... seem to be ignored?) in
devel/sage/sage/schemes/elliptic_curves/ell_rational_field.py
File "/Applications/sage-3.2.1.alpha1/devel/sage/sage/schemes/
elliptic_curves/ell_rational_field.py", line 4071:

4. numerical noise in devel/sage/sage/plot/plot.py, seems to be
related to #4572, and in particular '4572-maxima-float-fixes.patch':
