Today FreeBSD will have its 5.3-RC1 if there is no other problem occours. I have sent a private mail to Doug Barton about a strange issue I have in BIND9, however, it does seem to be serious enough nor it is clear to determine the impact. I may post it later on a public list.

5.3-RC1 is also the point that I can suggest you to install 5-STABLE instead of 4-STABLE because most of the show-stopping issues are addressed and being corrected.
