You will need Xcode5 for building it from sources:
git clone https://github.com/binaryage/asepsis
cd asepsis
git submodule update --init
rake build
rake install
sudo reboot
Note: for installing debug version which is more verbose in Console.app use rake build_debug instead of rake build. Also you may then run rake debug_test to check if asepsis works as expected.
Note: before rake build you might need to open Asepsis.xcodeproj once in Xcode. For some reason the xcodebuild hangs without that.
asepsisctl uninstall
