How to Remove a half-installed broken add-on?

[joejoejoe]

I'm in a ZC cleaning mode. Next item to be cleaned is to finish removing a broken add-on module: Google Froogle. I started to install it about 9 months ago. I never got it working - i got it to show on the admin panel under tools but that was as far as I ever got. Then when I moved my store over to a new server I left a few things that might have said google froogle behind. (I don't remember if they were files, or a folder.) Today while surfing around the control panel I noticed the tools menu still said "Google Froogle". Just looking at it gave me an error log:
PHP Warning: opendir(/home/myname/public_html/GOOGLE_FROOGLE_DIRECTORY) [<a href='function.opendir'>function.opendir</a>]: failed to open dir: No such file or directory in /home/myname/public_html/certainunmamedadminfolder/googlefroogle.php on line 185


How do I finish the uninstall since I no longer have the file(s) or access to any uninstall script, which probably wouldn't run if parts were missing?
