Hmmm.... Not sure, but if you use apt-cache show webalizer it says that 
it is dependent on either libgd2-noxpm or libgd2-xpm. It may be that 
this leaves this dependency as something you need to install on your own 
as apt-get isn't able to figure this either/or dilemma out on its own as 
this would seem to be very much an admin sort of decision, not an 
installer decision.

The same information given by apt-cache show webalizer can be verified 
by searching the Debian repositories on using the package search page on 
the official Debian website.
