Comment (by jpflori):
FYI, from the errors I had reported at:
* https://groups.google.com/d/msg/sage-devel/DhJcPuFIlPo/ToQuuJzu_BMJ
except for the ones fixed by #13151, this fixes the error in
* sage/crypto/mq/sr.py
although I still get an error in
* devel/sage/sage/interfaces/expect.py

Note that running singular('2+3') in sage works fine and so does the
second problematic doctest.
I still get the numerical noise problem from
* sage/rings/polynomial/polynomial_element.pyx
which is undoubtly unrelated,
and bunches of timeouts, but now I even get those on quite powerfull and
recent computers...
Oh and I still had troubles building singular because of C++ headers the
system has in /usr/local/include which seem incompatible with the ones
Sage's GCC ships, and this path is added by Singular in
src/Singular/Makefile[.in] to CPPFLAGS if gcc version is greater than 4.
You could argue that it is the computer install itself which is ill-
configured, but when removing the -I/usr/local/include from
Singular/Makefile[.in], everything builds fine.
I've opened a ticket upstream but thanks to Singular serving their http
server on a unusual port, i cannot access it at the moment.
