Internal copies are not that good usually, even if the size is pretty limited, as they are not shared between processes that might be loading the same library. Using the provided popt does save a dependency, but it's kinda a moot point, as popt is a dependency of rsync, and rsync is in system, so the presence of popt is almost universal. Just removing the --with-included-popt parameter fixes the issue for good. HTH, Diego
