[Devmon] Issue with new install

[Geoff H. <geo...@gm...>]

I just installed version 0.3.1 beta 1 and I am getting an undefined error.
Here is my configuration:

- CentOS 6.2 (Linux name 2.6.32-220.el6.i686 #1 SMP Tue Dec 6 16:15:40 GMT
2011 i686 i686 i386 GNU/Linux)
- Perl, v5.10.1 (*) built for i386-linux-thread-multi
- Xymon 4.3.7
- SNMP_Session: perl-SNMP_Session-1.12-4.el6.noarch

When I try to read the hosts.cfg file, I get the following error:

[root@xymon devmon]# ./devmon --readbbhosts -vv
[12-01-21@17:38:51] Option 'bblocation' defaulting to:

Any help is appreciated. Thanks, Geoff.
