Well git for IRIX is too old to work properly, and it's a nasty piece to compile last I checked.
An alternative is to tar it up, upload it here to the forum or elsewhere, and someone, (e.g. me) can make a git repo. Similarly, transfer it to a modern PC and doing it that way is more feasible.
There are newer binaries of git, but it's a pain. The RSE stuff is onerous to install and setup properly, IMHO. It's also overkill.

Technical problems should be sent my way.
