We use build scripts for Boost that ensure that we get a consistent 
build and they fill in the number of processors they find on the machine.

On our Ubuntu machines this works:
bjam -j`grep -c ^processor /proc/cpuinfo`

And on Windows this does:
bjam -j%NUMBER_OF_PROCESSORS%

The scripts are available at svn://svn.felpar.com/external/Boost
