Is there anyone know how to install boost.python. The website said most
boost libary are implemented entirely within their header files, but the
makefile for linux have libboost_python.a, so I assume boost.python is one
of the exception. Basically, I havenot been able to run a single example
successfully. Any idea? Thanks.

I am using linux 7.1 with KCC 4.0e, gcc2.96 is kind of ok.
