They're not separate methods.  The user-config.jam entry is necessary
because Boost.Build's auto-configuration for Python doesn't look for
debug builds of Python.  Even if you add that entry, if (as above) it
isn't the only instance of "using python," you will need
"python-debugging=on" on the command-line.  To get both variants built
in one bjam invocation,
you can use

    python-debugging=on python-debugging=off

or

    python-debugging=on,off

HTH, and sorry this took so long.
