Details:

Hi there,

I am not sure if this is considered a bug. I am a Gentoo user, everything is
built from source there. So it's important to know the dependencies of a
package. For ddd, elfutils is not in the dependency tree, because it also
builds fine without it. But if it is available anyway, ddd does link to
libelf.

So, when cleaning up unneeded packages, Gentoo lists elfutils as a package
nothing depends on, but then realizes that the ddd binray links to libelf
nevertheless, and complains.

This is no serious problem, but it's not nice as well, giving the users some
confusing output.

So, a solution might be some --with[out]-elf switch for the configure script
to control usage of libelf. I do not know what libelf is being used for, what
is needed instead if it if not available, and if there also should be a switch
for that.
