If that starts to happen too much, we'll need to rethink this feature.
It is supposed to be extremely reliable, and this should not rely on
tools that might not be installed, because giving clueless users a
tool that fails unless one "tinkers" is not a good idea, IMO.

I'll leave this bug open for now.
