Comment:
I believe this is fixed. I just ran the following on geom.math using the
modified spkg-install attached to this ticket:
{{{
#!sh
for i in `seq 1 16`; do
export MAKE="make -j$i";
time ./spkg-install &> /home/malb/scratch/singular-build-log-$i;
tail -n 3 /home/malb/scratch/singular-build-log-$i;
done
}}}
The output
