As always, you can get the latest beta version from the "develop" git branch. Alternatively, the self-contained source tarball is at http://www.sagemath.org/download-latest.html

"make" and "make ptestlong" both succeed on my MacBook pro, Mojave 10.14.6.

Pulled fresh clones of the develop tree on the usual three macOS systems:
10.13.6 (2017 iMac Pro, 18-core Xeon W)
10.14.6 (2017 MBP Pro, Quad-core Core i7)
10.15.4 (2019 MBP Pro, 9-core Core i9)

In each case, the build completed without complaint, and all tests (‘ptestlong’) passed!

On Debian testing running o core i7 + 16 GB RAM, pulling Trac#28656 on top of a 9.1 rebuilt from make distclean (using all the system packages ecommended by ./config) leads to 11 failures (and 1 timeout, which doesn’t when ran standalone) :

File	Result	P/T
src/sage/schemes/elliptic_curves/ell_number_field.py	3 doctests failed	P
src/sage/tests/parigp.py	Timed out	T
src/sage/rings/number_field/number_field.py	7 doctests failed	P
src/sage/rings/number_field/number_field_element.pyx	1 doctest failed	P
src/sage/rings/number_field/number_field_ideal.py	2 doctests failed	P
src/sage/tests/gap_packages.py	1 doctest failed	P
src/sage/numerical/backends/glpk_backend.pyx	1 doctest failed	P
src/sage/lfunctions/dokchitser.py	2 doctests failed	P
src/sage/rings/polynomial/polynomial_quotient_ring.py	2 doctests failed	P
src/sage/lfunctions/pari.py	1 doctest failed	P
src/sage/libs/glpk/error.pyx	1 doctest failed	P
src/sage/rings/number_field/unit_group.py	1 doctest failed	P

The result of re-running these failures is in the attached chkerrs.txt.

Most of these errors were reported for 9.1.rc3, and explained away by Jonathan Kliem. One of them is related to the optional gap_packages package.
