You might want to get in touch with its author, as he may be doing something with propellor on OSX. Anyway, I'd probably merge OSX patches, if they were not super intrusive. And I don't see why it would be, as propellor already supports FreeBSD. Since `Property` is parameterized by the operating systems it supports, it should be easy to start by only porting the core parts of propellor, and then port over individual Properties one by one as needed. See the commits for the recent FreeBSD port for a nice walkthough of the changes you'll want to make. """]]
