Problems with pingToRebuild.cgi

I previously used pingToRebuild.cgi to rebuild my blog whenever I posted an elsewhere link to the site. This worked great with Movable Type 2.6, but it appears that the script does not work with MT 3.0. I’m not sure if it’s my configuration or the script, but I simply can’t get it to work. Does anybody else have a solution for rebuilding a blog that uses the GlobalListings plug-in to display entries from two different blogs on one page? I can’t simply use PHP includes because the entries are displayed inline.

I’m considering using a cron job to rebuild the front page periodically, say every couple of hours. However, this would unnecessarily tax the server since I don’t post that often.
