Which it does while in subdirectory origsrc but it did not copy the 
scripts there before. Looks like a bug for me.

Logging the git function shows it's calling git submodule update (what's 
the purpose of that?) and hanging there.

Why should it tar the download to copy it over to src or where else; 
sure it's doing that?

Maybe just "Shells" then, as there are no data packages in Graphics.
