[C++-sig] Using boost.python with Makefile (no bjam)

[Philipp Münzel]

I added -lpython2.6 to the linker command, but I didn't change anything.
Obviously, the missing symbols are boost symbols and not python symbols,
since their names
_ZN5boost6python6detail11init_moduleEPKcPFvvE
clearly refer boost.

I built boost_python with the following command:

sudo ./bjam install -q --layout=system --with-python toolset=gcc
variant=release link=static threading=multi runtime-link=static

What is missing here?
