I was confused about this as libcap is in [extra] so how can it make
problems with a package in [core]?
So going from this comment in the bug report about libcap
(http://bugs.archlinux.org/task/11917#comment41046) I get...
> readelf -s /usr/sbin/syslog-ng | grep cap
33: 00000000 0 FUNC GLOBAL DEFAULT UND capset at GLIBC_2.1 (4)
177: 00000000 0 FUNC GLOBAL DEFAULT UND capget at GLIBC_2.1 (4)
473: 08228bd8 4 OBJECT GLOBAL DEFAULT 26 OPENSSL_ia32cap_P
Looks like libcap is a soft dep there. How?
Then rebuild in clean chroot:
> readelf -s syslog-ng | grep cap
467: 08221b18 4 OBJECT GLOBAL DEFAULT 26 OPENSSL_ia32cap_P
And then the dmesg warning goes away... So, the lesson to learn is to
_always build in a clean chroot_!
