Linux system to use pkgsrc?

["Thomas Mueller" <mueller6724%bellsouth.net@localhost>]

What is a good type of Linux system if one wants to build packages from pkgsrc 
as opposed to using a full ready-to-go distribution like Slackware, Debian, 
Ubuntu, Fedora, etc?  Linux does not have a BSD-style base system, but it is 
clearly necessary to have the gcc tools and other standard Unix utilities 
(mount, ls, sed, grep and many others).  Compile natively or cross-build?  
Building packages from pkgsrc would be the intent in choosing the starter 
Linux; I would be starting from a blank partition.
