I have found a great deaal of duplication in install trees, particularly 
when you just want to install the latest.  I've managed to get some 
massive savings with NIM on AIX and some lesser but stll very good savings 
with CentOS by building parallel trees and hard linking the files.

It's what I can remember in time to use.
