Yup, I'm out there...

What kernel and what distribution? Build instructions and what bits to build vary a little based on that info...

Ah. So if everything bug lirc_zilog is building, you must be running a distribution that includes lirc patches in its kernel, but doesn't include lirc_zilog. In that case...

make CONFIG_LIRC_ZILOG=m -C /lib/modules/kver/build M=$PWD modules

...should get it built.
