    I didn't meanwhile sync my laptop or run "emerge", I had just shut it
    down and booted it again today. I know that Windows users often make problems vanish by rebooting -- but I hadn't yet solved any problem by rebooting my Gentoo laptop ...

    Anyway: this problem HAS vanished -- possibly by rebooting.

    Sorry for the noise :-)


    Sorry for the confusion I guess, but I *fixed* it.

    https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=c929acd0831aa3e50729a4af6516fc94f779d3ce

    https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e82cd942598f18e4a8df26c2b5b1d61c7880fc59

    The fix means new binary packages will build without using those
    libraries at all. It also added a new build dep, so the binhost
    recompiled them, hence newly running "emerge --oneshot --getbinpkg media-libs/libraw media-libs/libcdr" will get the fixed version.


    As I said privately to you -- it is still a revdep-rebuild bug IMO --
    please report it. ;)

    Am I correct in assuming that you "fixed" it by teaching these two pack-
    ages to circumvent a bug in "revdep-rebuild"?



    Yes.

    please report it. ;)

    Ok, but what am I expected to put into the bug description, now that my original command sequence is producing the expected result? I can hard-
    ly write 'Package "revdep-rebuild" is buggy. Ask Eli for details.' can
    I? :-)


    "revdep-rebuild sometimes insists to rebuild packages that do not
    trigger portage's own preserved-libs feature. Originally noticed with
    libraw and libcdr. Eli Schwartz analyzed it and said that the new
    package still provides a symlink for the old file. See https://public-inbox.gentoo.org/gentoo-user/[email protected]/
    for details."
