Yes.  Otherwise MPI will default to 32 bit and return 32 bit  
libraries if -m64 is not passed.

Here's the command line I run for the nightly tests.

python run.py --proxy="http://wwwproxy.sandia.gov:80" -- 
runner="Sandia-sun" --bjam-toolset=sun --pjl-toolset=gcc -- 
toolsets=sun-5.10 --bjam-options="-j27 stdlib=sun-stlport address- 
model=64"
