>From the guide, regarding parallel builds (in the build phase keywords section):

use_parallel_build
This keyword is for specifying whether or not it is safe for a port to
use multiple CPUs or multiple cores in parallel during its build
phase. If use_parallel_build is not set to “no” in a given port, the
option -j${build.jobs} is passed to ${build.cmd} (if ${build.cmd} is
make or scons).

Why would it pass -j${build.jobs} if use_parallel_build is set to NO?
Wouldn't you want to pass -j1 in this case, since by default
${build.jobs} will be the number of cores (unless low memory)?

Maybe this is just a typo and that "no" should be a "yes" or else I am
confused :)
