OK, just compiled elfutils-0.170 without errors. And it indeed does *not* provide libelf-dev (or so).

I also could not find any indication how to build it in the accompanying docs. Should there be a ./configure switch it's well concealed.

It's hard to believe that the only source for libelf-dev should be the "distro". I guess that would be a first.

So long!
