Well I don't see anything that would make it not build with the same 
compiler as the others. Are you sure it's not just a leftover from some 
previous build? Could you do a build with the "-d+2" option to see which 
commands it's invoking to compile? To verify that it's always using the 
cross compiler.

The includes only show up if you do "install". Since you obviously don't 
want to obliterate your system Boost install you'll also have to specify 
the "--prefix" of where to install :-)
