[Sshguard-maintainers] bug?

[hays <bil...@un...>]

I'm trying to get sshguard working with valid users under OSX. At first I thought it was a signature issue, and perhaps it is, but I'm not conversant enough to figure it out. Here's a debug listing:
tomthumb:sshguard hays$ env SSHGUARD_DEBUG=foo /usr/local/sbin/sshguard
whitelist: add '127.0.0.1' as plain IPv4.
whitelist: add plain IPv4 127.0.0.1.
Started successfully [(a,p,s)=(40, 420, 1200)], now ready to scan.

Not sure what 
Next token is token WORD ()
Error: popping nterm text ()
means, any ideas?
