(2) Some numerical noise, that perhaps requires more tolerance:

FWIW, builds okay on Debian testing running on Core i7 + 16 GB RAM.

initial ptestlong showed two failures :

----------------------------------------------------------------------
sage -t --long --warn-long 66.2 src/sage/interfaces/expect.py  # 1 doctest failed
sage -t --long --warn-long 66.2 src/sage/schemes/projective/projective_morphism.py  # Timed out
----------------------------------------------------------------------

However, both tests pass "standalone" :

charpent@asus16-ec:/usr/local/sage-6.8$ sage -t --long --warn-long 66.2 src/sage/interfaces/expect.py
Forcing sage-location, probably because a new package was installed.
Updating various hardcoded paths...
(Please wait at most a few minutes.)
DO NOT INTERRUPT THIS.
Done updating paths.

It is easy to understand for the first test, but the second one stimyes me...

Built w/o problems from the tarball, and all tests (‘ptestlong’) passed on OS X 10.10.3.

I noted one issue that I haven’t seen before (which can be annoying when actively using the system while building): continual, frequent “modal” alerts saying that I have to install the Java runtime in order to do something or other. In the past, I recall only seeing one during the testing. That may be because I don’t always actively use this system when building (I just kick off the build and wander off to other duties).

Has there been a change here?

Thanks!

I guess the easiest solution is to install Java ;-)

The popup comes up whenever somebody runs "java". There is a java binary in the path, so its completely legit for configure tests or anything else that *might* use java to try to execute it. Except that Apple decided in their infinite wisdom that "java" should pop up a dialog.

Built w/o problems and all tests ('ptestlong') passed on OS X 10.6.8 (Dual 6-core Xeons). No problem with 'java'... :-}
