I found someone with OS X 10.4, and we built 1.1.3, 1.1.2, and
1.0.something.  They all failed in similar ways to what you are
reporting.

In radiusd.conf.  They only cause problems at run time.

The problem is that these modules try to use symbols from the radiusd
binary, and the OS X linker isn't very clever about dlopen'ed modules or
plugins - it has a whole other way of doing it with namespaces and so
forth that fails in this instance.  This part of the discussion (how
linking works) is starting to wander off topic for this mailing list,
but I'd be happy to talk about it or give you pointers to links to learn
more on your own off list.

Take care,
