Mirrors:
   http://mirror.aarnet.edu.au/pub/LPRng/LPRng/

Need to do the following as root:

rm /usr/local/share/LPRng; ln -s $V /usr/local/share/LPRng
chown -h -R root.bin $L
#ksh -c 'cd $L; for n in sbin/lpc bin/lpq bin/lpr bin/lprm bin/lpstat; do mv -i \$n \$n.real; cc -o \$n -DREAL_PROG=\"\\\"$L/\$n.real\\\"\" /usr/local/share/root/sec_wrapper.c; chmod 0711 \$n.real; chown 0:0 \$n.real \$n; chmod 4711 \$n; done'
ksh -c 'cd $L; for n in bin/lpc bin/lpq bin/lpr bin/lprm; do mv -i \$n \$n.real; cc -o \$n -DREAL_PROG=\"\\\"$L/\$n.real\\\"\" /usr/local/share/root/sec_wrapper.c; chmod 0711 \$n.real; chown 0:0 \$n.real \$n; chmod 4711 \$n; done'
ksh -c 'for n in 1 5 8; do cd /usr/local/man/man\$n; ln -s ../../share/LPRng/man/man\$n/* .; done'

You need to do (on each machine):
ln -s /usr/local/share/LPRng/etc/lpd.conf /etc
ln -s /usr/local/share/LPRng/etc/printcap /etc

You may also want to do (on each machine):
ksh -c 'for n in /usr/*bin/lp* /usr/*bin/cancel; do m=\${n##*/}; if [ -f /usr/local/share/LPRng/bin/\$m ]; then mv -i \$n \$n.DEC; ln -s /usr/local/share/LPRng/bin/\$m \$n; fi; done'
