Bugzilla Bug 179280

The reason for it seems to be that the build looks for the dns_sd in
../mDNSPosix/build/prod/ while it has just been created in
../mDNSPosix/build/debug/ (see below).
Building without the debug use flag works without problems.

Confirming, without debug builds ok, with debug fails on linking with dns_sd

Looks like this will require the build system files to be patched. Anyone have
the time to do the honours?

On a second thought, you might want to overwrite -r5 instead of adding -r6,
sparing a rebuild for those who built it with -debug, they are not affected by
the update anyways.

And feel free to flame me about the submission screwups or the submissions
themselves, I'm new.

Diffs to the existing ebuild are far more useful than posting the whole ebuild.
We are mostly interested in what you have changed and can apply the patch
ourselves. I will look into this shortly and look at integrating it. Thanks for
taking the time to work on this - much appreciated :)

Thanks for the patches - went with a slight variant but it seems to work well
and should be easier to maintain using a sed statement. Ideally the Makefile
should be patched in a form that could be applied upstream...

still does not work for me
