PHP uses only one CPU on a dual core

I downloaded and compiled the source for PHP 5.3.0 running on CentOS. The installation worked fine; however, when executing a script from the command line (doing some heavy calculations), I see that only one CPU is being used, the other remains at 0%.

Is there any switch (e.g. when calling make) that could enable the use of the two CPUs by PHP?
