For sake of completeness: There is an alternative implentation in C for Plan 9 that I've used and is now mature enough that the 9front project switched to it from Mercurial. It might be possible to compile it with the plan9port compiler wrapper. There is also a Git implementation in OCaml that some MirageOS unikernels use to serve static content from a git repository. Also the Irmin "database" is based on git and is written in OCaml.
