That is one option, and if you have few variables, it's a good option,
imho.

The string manipuliation would pe pretty simple, because you only have
to strip the leading slash:
(r'^' + settings.MEDIA_URL[1:] + r'javascript/site.js$', media_js),

I don't think it's any easier, but it might seem a little more
elegant: create a .js file only for the MEDIA_URL variable, and have
it generated from Django, served via urls.py. That way you keep your
large javascript code in a static file served by the web server, and
you don't mess up the HTML with embedded javascript.
