Milter-greylist

Running FBSD-6.0-p9

I've just hit a brick wall on trying to build/install the new gl-2.1.9

Never had any problem installing previous versions, although I've only
reached gl-2.1.5-patched. Trying to re-install that older version gives me
the same error on build. Thus, I guess something has changed on my system.

Any advice on how to get by this error would be appreciated. I am an admin
and not any good at code. Here's the error I get on any of my servers
trying to install:
