Boost is annoying

[John Marino <netbsd%marino.st@localhost>]

It seems that everytime Boost is updated, packages break, perhaps at a 
rate faster than they get fixed (e.g. games/flightgear remains broken)

I'm seeing 3 more packages recently (likely) broken because of boost update:
editors/Sigil
games/wesnoth
cad/openscad

Should there be some kind of policy specifically for Boost?  Or do we 
want to keep updating it every 2-3 months and constantly deal with the 
breakage?
