i've received a few reports of this, but no one's given me enough useful information to definitively fix it yet. the problem seems to be that Panther may stick the log files in different locations under certain situations.

if you redownload now, the installer should complete.... but if you don't have a file at /var/log/fax/cu.modem.log, fax status simply won't work.

if you encounter this problem, please do a little sleuth work in the Terminal to find any files named "cu.modem.log" and let me know where it is and what machine, and what exact version of OS X you're running.

on the four macs i have here, and the dozens i have access to at my day job, every last one has the /var/log/cu.modem.log file, so I'm not sure yet when and where OS X might do different things.
