	From my reading of the ticket, it appears to be git that is causing the
"problem". I'm just setting up a simple dev environment, basically an
editor and a compiler. So far, in my stuffing around, I've see no
problems. I'm about to copy across the final "install" and give it a
flog so hopefully, fingers crossed, it works.

	Thanks for the help.
