The different varieties of linux make installation an adventure.
Basically you need libpcap and pcre for the front-end ourmon probe,
and perl/rrdtool for the backend.  And a web server to serve it
up (apache2).

Here are some clues:

1. fedora:

- Downloaded libpcap from http://www.tcpdump.org, ./configure, make and
copied the libpcap.a into /usr/lib

   - yum install libpcap-devel pcre pcre-devel rrdtool rrdtool-perl

2. ubuntu:

See the ubuntudep.sh shellscript.  In theory this may
cover debian too.
