I have compiled it with the IPv6 option.
I don't think you could have (you do so by configuring using
"./configure --enable-brov6"), because currently the sources
don't compile due to the introduction of uses of addresses
(for example, in bro.bif) which need additional code to build
when addresses occupy > 1 word.
As I mentioned, this will eventually be fixed, but it's not
a priority for us at the moment due to more pressing needs.
If you want to contribute patches, that would certainly
be welcome.
