error messages

I'm running grepmail 5.3033-2 on Ubuntu 8.04.

Trying to run the app and got this:

[holtzm@localhost]~$ grepmail -bBR 'not connecting' /home/holtzm/mail > 
/home/holtzm/mail/network
Use of uninitialized value in print at /usr/bin/grepmail line 1663.
Use of uninitialized value in print at /usr/bin/grepmail line 1663.
Use of uninitialized value in print at /usr/bin/grepmail line 1664.
Use of uninitialized value in print at /usr/bin/grepmail line 1665.
Use of uninitialized value in print at /usr/bin/grepmail line 1666.

There were messages in /home/holtzm/mail/network but it looks like too 
few. Looked at /usr/bin/grepmail but not being a programmer I saw no 
problems.

I have used this app in the past and it always performed flawlessly.

Any thoughts, ideas, comments or help appreciated.
