Actually there is even a further optimization I had forgotten about...
The ability to build outside of the sandbox. Things like gcc and glibc can 
build this way.
IF the makefiles/configure scripts for the library are configured correctly 
you should be able to do something like the following:
machine1: cd /nfsed/librarysource
machine1: cvs update -dP
coffee mess: drink 2 cups;use restroom
machine1: cd /libbuildlocation/
machine1: /nfsed/librarysource/configure \
        --PREFIX=/my/install/location;make;make install
machine2: mount -t nfs -oro machine1:/nfsed/ /nfsed/
machine2: cd /libbuildlocation/
machine2:  /nfsed/librarysource/configure \
        --PREFIX=/my/install/location;make;make install
machine3-n: mount -t nfs -oro machine1:/nfsed/ /nfsed/
machine3-n: cd /libbuildlocation/
machine3-n:  /nfsed/librarysource/configure \
        --PREFIX=/my/install/location;make;make install

because everything is using the same source.
