Right, but can the GPL'd program integrate non-GPL'ed source? E.g., can MediaWiki use non GPL'ed source code?
No. Combining source code, at least in the view of the GNU Project, constitutes forming a derivative work of both sources of code. Any derivative work of a work used under the GPL must itself be licensed under the GPL. (This interpretation has not been tested in court, of course, but the WMF is pretty unlikely to disrespect it.)
