Long story short, in systemd-209 the libsystemd-* libraries were removed and replaced with single libsystemd. We install compatibility libsystemd-*.pc pkg-config files, so apps using pkg-config are not affected (yet :)). Since this package tries to link libsystemd-daemon directly, it fails terribly with >=systemd-209. The possibilities are: 1. use pkg-config to query libsystemd-daemon -- compatible with all versions but at some point we will be removing compat pkg-config files, 2. use pkg-config to query libsystemd, fallback to querying libsystemd-daemon -- future- and backwards-compatible, 3. just use libsystemd, and dep on >=systemd-210 in the ebuild (we didn't add -209). Preferably, always use pkg-config :). If you need any help, please let us know. I will attach a build log in a few minutes.

The easist way to do option 2 above would be to change line 24 of aiccu-*-systemd.patch to read: +LIBS += $(shell pkg-config --libs libsystemd 2>/dev/null || pkg-config --libs libsystemd-daemon) Instead of hardcoding -lsystemd-daemon there.
