Comment(by AlexanderDreyer):
> * 50 of 50 parallel installs of `singular-3-1-1-4.p1.spkg` succeed on
sage.math with [http://ccache.samba.org/ ccache] ''enabled''. However, 5
of the runs (not including the last) have the message `ranlib:
'libkernel_g.a': No such file`. Is this a problem?
[http://sage.math.washington.edu/home/mpatel/trac/9733/singular-3-1-1-4-j20.log.6
Here's] a sample log file. After the last run, I ran the long doctests.
They pass.
I think I have fixed that issue, see the patche above and the new spkg at
http://sage.math.washington.edu/home/dreyer/spkg/singular-3-1-1-4.p1.spkg
(same place)
> * Are the object files for `libcf.a`, `libsingcf_g.a`, `libfac.a`, and
`libsingfac.a` built in parallel?
From the Makefiles there's no restriction, so the dependencies of each of
which can be build in parallel. But there may be dependencies, that that
there is no parallel build in fact.
> * Is the message `install: libsingcf_p.a does not exist` harmless?
It's printed three times per install.

> I did all of the runs above under `/scratch`.
As fbissey said, this should not cause problems here.
