[Message part 1 (text/plain, inline)]

Actually, no, installing git does not help resolve the problem whatsoever. One works, the other two don't, but I can't tell why. The one that works is my general purpose development container, and the other two are more specialized, so that may be the origin of the problem, but it doesn't explain what in particular is missing. What does project.el rely on the host having installed?
