A clean solution implements HP-UX 10: it has two files called
/etc/PATH and /etc/MANPATH which contain a colon-separated list of
paths to binaries/manpages of the installed packages (which reside
usually beneath /opt, BTW). These files are read by /etc/csh.login and
/etc/profile and every new package that wants to add entrys to $PATH,
just modifies those files.

Just a thought,
Jochen
