Error installing nfsen on Debian Squeeze

Trying to install nfsen on Debian Squeeze, running:
#./install.pl etc/nfsen.conf

would produce an error:

Can't create channel directory: '/srv/nfsen/profiles-data/live/peer' File exists
No collector started!

This is due to trying to install into a custom directory.
Edit etc/nfsen.conf and change to:
$BASEDIR = "/usr/local/nfsen"
(may need to create the directory first?).
