this is exactly what i'm talking about...

and especially this where both were used at one time... we didn't have to worry 
then because we didn't have a working IPv6 in our package... but now we have 
people taking it onto themselves to forcibly upgrade snort because they can't 
get any new rules and they are under the mistaken idea that they /have to have/ 
new rules all the time... like the old ones are going to go stale and stink up 
the place or something... so they go thru everything to get a working binary in 
our development package and install it only to find it falling over or not 
logging anything and it is starting to look like it is coming down to the use of 
var and/or ipvar in some cases...
