On the gcc-3.1 version of Apple for Darwin/MacOS X I got it to
work just by adding another include:

#include <iterator> // std::ostream_iterator

I have sent the patch with a few extensions to boost::random to
Jens, but I guess fixing this is more urgent than the extensions
I sent to Jens. The same patch is needed in 
boost/random/mersenne_twister.hpp

Best regards,
