Hi Will!
I have no perl skills but this error is caused when apache2 decides that there 
is no additional hosts to serve than the default. In Debian/Sarge apache2 is 
configured with multiple small configs for each site rather than listing them 
in apache2.conf. (just covering the basics) the default site needs to be 
replaced with the file /etc/apache2/sites-available/yourmainhost which is 
symlinked to /etc/apache2/sites-enabled/@yourmainhost the first line of this 
file works best for listening on all ports if it is set to 
"NameVirtualHost*:80"  DO NOT INCLUDE THIS LINE IN ANY OTHER SITE CONFIG THAT 
YOU MAKE!  Then you can create as many other sites as needed by creating the 
files /etc/apache2/sites-available/yoursecondhost which is symlinked 
to /etc/apache2/sites-enabled/@yoursecondhost and so on. I also think (just 
an idea) that you might want to only use an "Include" statement for you perl 
script at the end of apache2.conf and put that script elsewhere so that if 
you need to modify the perl script you don't have to completely start over 
but only modify it and restart apache2:-) All this is based on guessing at 
what type of VirtualHost you are running, but I use name based as it is much 
easier to configure that a system using ip addressing.
BTW none of this is in the new manual or the Debian docs that I coul find.
Best wishes.
