Comment(by jhpalmieri):

 This also works for me.  I could force the old version to fail when
 building in parallel (on sage.math: `MAKEFLAGS='j -l8' ./sage -f ...`, and
 similar on OS X).  With the new spkg, it has built every time on sage.math
 (using both `-l30` and `-l2`).  On OS X, I had one failure with the new
 spkg using `-l8`, although I've had 4 successful builds that way.  The
 machine only has 2 cores, so `-l8` is probably a bad setting anyway.  With
 `-l2` on that machine, no problems.
