On OS X, 10.11.3 (Quad core Core i7), build completed w/o problems. Testing
(‘ptestlong’) showed one failure that was repeatable when the whole testing
phase was rerun; but does not repeat when the test was run by itself. One
example is below. The failures showed essentially the same output:
sage -t --long --warn-long 107.9 src/sage/modular/modform/ambient_R.py
Killed due to segmentation fault

Unhandled SIGSEGV: A segmentation fault occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.
