The rootd and proofd startup scripts:

rootd         - rootd startup file for RedHat based systems (/etc/rc.d/init.d)
rootd.xinetd  - rootd startup file for xinetd (/etc/xinetd.d)
proofd        - proofd startup file for RedHat based systems (/etc/rc.d/init.d)
proofd.xinetd - proofd startup file for xinetd (/etc/xinetd.d)

ch.cern.rootd.plist  - rootd MacOS X 10.4 launchd script
ch.cern.proofd.plist - proofd MacOS X 10.4 launchd script

Modify the path in the above two scripts as needed and copy both files to
/Library/LaunchDaemons/ and do:

launchctl load /Library/LaunchDaemons/ch.cern.proofd.plist
launchctl load /Library/LaunchDaemons/ch.cern.rootd.plist

at reboot the rootd and proofd will be executed again.
