Built w/o problems on Mac OS X (10.8.4, Quad-core Core i7). All tests ('ptestlong') passed on each system!

On 10.6.8 (Dual 6-core Xeons) I have run the full build three times. Each time, the build fails in devel/sage/sage/tests/cmdline.py line 184) with a timeout.

In fact, it seems to fail many times, because a bunch of tests are run many times.

I just noticed this; is it expected?

I assume you mean that doctests fails, not that the build process fails.

The test you mention runs ./sage -v which executes (in spkg/bin/sage)
exec sed -n -e 's/.*\(Sage Version.*Date: [0-9-]*\).*/\1/p' \
"$SAGE_LOCAL"/bin/sage-banner

This actually changed in #14733, so that ticket might be to blame.
Could you apply the patches from #14733 to an earlier build of Sage to
check if that reproduces the problem? Also list your environment please
(run "env" from a Sage shell).

> because a bunch of tests are run many times.

What do you mean with this, please elaborate.

I'm on the road for ~2 weeks, so I can't do this now (my 10.6 system is the Mac Pro; the laptop is 10.8). If I run into one while traveling I will try it.

>> because a bunch of tests are run many times.

The log file shows the tests repeatedly. I don't know whether this is an artifact of the "make -jn" command, but for example, I get 23 copies of
sage -t --long devel/sage/sage/tests/cmdline.py
and 23 copies of others as well, e.g.,
sage -t --long devel/sage/sage/schemes/hyperelliptic_curves/hyperelliptic_padic_field.py

Haven't checked whether this is true for all tests (on the 10.6 system, a dual 6-core Xeon, I use "-j24": 12 cores, 2 threads-per-core).
