The user could delete hexl, if he doesn't use hexl-mode and doesn't want

Also, it could have failed building for some reason or other.

I don't know, I didn't write the code, but I suppose the reasoning is
that one or the other are very likely to be around... and if they don't,
well, you'll get an error anyway.
