Mac OSX Synfig Installation Not Working

Hello! I downloaded the Mac OSX SynfigStudioMac.dmg, and when I run Synfig Studio.mpkg inside the SynfigStudioMac.dmg, everything is dandy until I get to the actual installation. It starts to install, but then says, “The installation failed. The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.” I have tried to re-install it a million times, but I always get the same error message. I hope you guys can help! Thank you!

Please contact the current packager of the dmg file. I think he is secondplanet. Also there is a warining in the download stating that it is currently untested on some OS versions.
