[otrs] Help finding installer.

I see that the installer.pl file used to set up the system should be in OTRS' root web directory, but it seems to be buried in "www/otrs/bin/cgi-bin/installer.pl" instead. I tried many different versions, and then just moving everything (as a last resort) to where the documentation says the installer script and every other webfile should be, but to no avail. What am I missing? Thanks :) . Dustin Oprea
