I downloaded PBGL from here:
http://osl.iu.edu/research/pbgl/

When running CMake, it said that it couldn't find boost_mpi. I read that I need to do 

./bjam --with-mpi

I did that and it seemed to be successful (though very very quick):

--------------------
Component configuration:

...
    - mpi                      : building
...

...found 1 target...


The Boost C++ Libraries were successfully built!
--------------------

So my questions are:

1) Does PBGL not come with the normal boost package from sourceforge (http://sourceforge.net/projects/boost/files/boost/1.44.0/)?

2) How can I tell if boost_mpi built properly?

Thanks,

David
