I'm not sure why this wouldn't be happening everywhere, but the new
setuid kdeinit stuff causes my ~/.ICEauthority file to be created
owned by root, which subsequently causes authentication errors and kde
fails to start:

---(snip!)---
xset:  bad font path element (#87), possible causes are:
    Directory does not exist or has wrong permissions
    Directory missing fonts.dir
    Incorrect font server address or syntax

KDE is unable to start.

now, according to configure.log it says it's not going to make it setuid:

---(snip!)---
checking whether to make kdeinit setuid root in order to protect it
from bad Linux OOM-killer... no
---(snip!)---

...and the Makefile.am *thinks* it's only supposed to do the setuid if
that says "yes":

---(snip!)---
if KDEINIT_SETUID
# start_kdeinit needs to be installed setuid root on Linux
install-exec-hook:
        @(chown 0 $(DESTDIR)$(bindir)/start_kdeinit && chmod 4755
$(DESTDIR)$(bindir)/start_kdeinit) || echo "Please make start_kdeinit
setuid root" >&2
        @echo ""
        @echo "start_kdeinit is by default installed on Linux with a
set SETUID root bit!"
        @echo "This is needed to prevent kdeinit from being killed by
a bad heuristic in the OOM-killer when running out of memory."
        @echo ""
endif
---(snip!)---

...but going by the install output, it's getting enabled anyways:

---(snip!)---
cd ./kdesu/ && /sw/share/unsermake/unsermake install-data-hook
99%
kgrantpty is by default installed with a set SETUID root bit!
This is needed for konsole, etc. to ensure that they can't be eavesdropped.

cd ./kdecore/ && /sw/share/unsermake/unsermake install-exec-hook
99%
start_kdeinit is by default installed on Linux with a set SETUID root bit!
This is needed to prevent kdeinit from being killed by a bad heuristic
in the OOM-killer when running out of memory.

cd ./kinit/ && /sw/share/unsermake/unsermake install-exec-hook
---(snip!)---

I can fix it manually for OSX now, but I wouldn't be surprised if this
bites someone else as well...
