Uninstalling RT?

Hello,

I downloaded and installed RT 4. However I forgot to use the
–with-web-user=apache and --with-web-group=apache flags when I installed.
Also I had set the --prefix=/usr/local without realizing the implications.

Is there a way to uninstall RT and redo the installation with new flags?

If that’s not an option, what a way to fix my current installation?

Thanks,
Amit
