It may sound strange, but /dev/lirc and the kernel drivers (like 
lirc_rpi) are not "Lirc" anymore. They now belong to, and are maintained 
with, the kernel. So you are on the wrong mailing list. I suggest trying 
the RPi forum. Also, the lirc_rpi driver is deprecated since some time, 
possibly it has been formally removed?

Good luck!
