The lirc device file doesn't exist.  I think that file should be created by
udev.  The atrpms mythtv-suite installs a lirc-devices rpm which addes a
lirc.rules to udev.  Those lirc rpms were compiled to use /dev/lirc0 thru
/dev/lirc9 while your binaries are looking for a /dev/lirc/0.  Maybe that
is a configure option for compiling lircd.

I have these devices:

[root at firkraag ~]# ls -l /dev/lir*
lrwxrwxrwx 1 root root     5 Dec 26 12:30 /dev/lirc -> lirc0
crw------- 1 root root 61, 0 Dec 26 12:30 /dev/lirc0
srw-rw-rw- 1 root root     0 Dec 26 12:30 /dev/lircd
prw-r--r-- 1 root root     0 Dec 28 00:44 /dev/lircm

You might need to use:

ls -l /dev/lirc/*


I guess that you either need to add a udev rule to create the lirc device
files at boot time or create them with the mknod command.  Something like
this:

mknod /dev/lirc/0 c 61 0

and maybe:

ln -s /dev/lirc/0 /dev/lirc
