Install fails on 10.10.5

[l0010o0001l]

This is a super exciting project that can most definitely be helpful! I tried running the install script and these errors were returned:

Installing the virtual audio device Background Music Device.driver to /Library/Audio/Plug-Ins/HAL.
ERROR: Install script failed at line 152. This is probably a bug in the script. Feel free to report it.
.ERROR: Install script failed at line 60. This is probably a bug in the script. Feel free to report it.
ERROR: Build step failed. See build_and_install.log for details.
Failed command:
