RANCID & package managers

[Netmanager]

So I want to make a RANCID package for a popular ports package 
manager for OS X (DarwinPorts).  I like all my open source apps to 
live in a special place.  Would it be better to install all of RANCID 
into the package's {prefix}/var/rancid or to just put the 
localstatedir (logs, repository, groups) there and let bin, etc, man, 
share go into the package manager's {prefix}/bin, {prefix}/etc, 
{prefic}/man, etc. amongst all he other packages stuff?  Opinions on 
whuch is a better way?  Thank you.
