No strndup on FreeBSD/OSX

[sirvaliance]

So on building Inverarity on OSX, the following error occurs:

Undefined symbols:
"_strndup", referenced from:
_load_distribution in dist.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

I will look for the best route to fix this issue.

I guess strndup was added in Lion, but otherwise the user has to create or add it themselves. Will continure to look into it.

Weird that it compiled in the first place. Are you sure there isn't some error before the linker?

Here is the full output of make:

Ick. I suppose it might be time to add an autoconf dependency. Or, since I keep meaning to learn cmake, to add a cmakefile.
