FWIW I'd consider two alternatives:

(1) forgo links entirely and use something like
http://modules.sourceforge.net/ to manage $PATH;

(2) instead of using the bundled create-links, have the /usr/bin scripts
check a per-user symlink and fall back to a system one; running the select
script as root sets the system symlink, running as user sets the per-user
symlink.
