This problems seems to be still present in 3.4 alpha2 on FreeBSD.

And looking at Linux, the problem seems to be present also there, just 
loading of syslog-ng does not fail as long as there are no smtp related 
options in syslog-ng.conf:

# ldd /usr/lib/syslog-ng/libafsmtp.so
     linux-gate.so.1 =>  (0xffffe000)
     libpthread.so.0 => /lib/libpthread.so.0 (0xb76dd000)
     libc.so.6 => /lib/libc.so.6 (0xb7570000)
     /lib/ld-linux.so.2 (0xb771c000)

If smtp is configured, syslog-ng gives no error messages, but does not 
start.
Bye,
