I found out the sources at http://truffula.com/rlpr/
Now, the Makefile is buggy.
I had to do this to install rlpr properly on OpenBSD. I post it here

just in case

you're interested.
make bsd-symlinks is wrong and ./bin is also wrong. The binaries go

into ./src/bin
spree(p8)| sudo make bsdlinks

cd src && make bsdlinks

installing bsd symlinks...

mv /usr/bin/lpr /usr/bin/lpr.bsd

ln -s ./bin/rlpr /usr/bin/lpr

mv /usr/bin/lpq /usr/bin/lpq.bsd

ln -s ./bin/rlpq /usr/bin/lpq

mv /usr/bin/lprm /usr/bin/lprm.bsd

ln -s ./bin/rlprm /usr/bin/lprm

spree(p8)| ls bin

spree(p8)| cd src/bin

spree(p8)| ls

rlpq  rlpr  rlprd rlprm

spree(p8)| sudo mv rlpr /usr/local/bin

spree(p8)| sudo mv * /usr/local/bin

spree(p8)| sudo mv /usr/bin/lpr.bsd /usr/bin/lpr

spree(p8)| sudo mv /usr/bin/lpq.bsd /usr/bin/lpq

spree(p8)| sudo mv /usr/bin/lprm.bsd /usr/bin/lprm
