/opt/local/bin/python2.5 as default MacPorts' "python" interpreter

Currently there is no official "python" interpreter for MacPorts (in the past there was a link to python2.3 even when python24 was installed, IIRC) but many Python programs (or their shebang lines) expect a "python" command in the PATH, otherwise Leopard's python2.5 is picked from its symbolic link "/usr/bin/python" and they don't work correctly. This is the case, for example, of Sudoku and Chess in gnome-games. I think that, similarly to the destroot phase of Tcl (ln -s ${prefix}/bin/tclsh8.5 ${destroot}${prefix}/bin/tclsh) an "/opt/local/bin/python" link should be created pointing to the 2.5 version, as MacPorts' "default" Python version.
