It's in many of the related branches in my fork:
https://github.com/dboddie/inferno-os
My changes have recently been merged into the official mirror of Inferno on GitHub as well:
https://github.com/inferno-os/inferno-os
If you have any trouble building the latest Inferno sources it will probably be due to the way libfreetype is included and built. The build needs an extra

  git submodule update --init

command to bring in the sources.
I've also pushed a fix to the freetype build process which didn't seem to be required when I tested it before making the original merge request:
https://github.com/inferno-os/inferno-os/pull/17

Let me know if you need help getting up and running.
