I've got warning during execution too :
> ./bro: ./bro : WARNING: symbol(__p_class_syms) size mismatch relink your program
> ./bro: ./bro : WARNING: symbol(__p_type_syms) size mismatch relink your program
Let me know if you still have this problem with the new 0.8a34 release.
Did you get the BIND dependencies worked out for OpenBSD?
