pppd gives that error unless you attain root through sudo, su1, or su
(or by logging in as root). In particular, making the executable suid
root will not work; pppd notices and gets rid of the extra privs.
Presumably you can recompile it with that option turned off or hacked
out; do so only if you will chgrp it to an appropriate group (wheel
or any other adminish group will do fine, just so that only people
who should fire up ppp are in the group) and set its world privs to
none.
