[Snort-devel] non-fatal warnings when loading snort-extras (with warn-all)

That specific output is just noise.  The snort_extra DAQs are installed 
in the same plugin path.  One way to avoid that is to use something like 
--plugin-path $snort_extra/loggers:$snort_extra/inspectors:etc (omitting 
$snort_extra/daqs of course).  If you so those messages for a non-DAQ 
lib that is significant because those libs aren't loaded.
