This came up on the Gentoo portage forum recently. What I do is this:

1. In /etc/conf.d/local.start add a line
tail -F /var/log/emerge.log | awk '{$1="";print | "logger -t emerge -p 
local5.info"}' &

2. In /etc/syslog-ng/syslog-ng.conf add lines to the effect of:

destination emerge { file("/var/log/emerge"); };
filter f_emerge { program(emerge); };

filter f_messages { level(info..emerg) 
        and not facility(auth, authpriv, mail, news, cron, local0, local6)
				and not program(emerge); };

log { source(src); filter(f_emerge); destination(emerge); };

Restart syslog-ng and there you go. :)
