db4 vs db43

Hi, I noticed we got a db4 port, which installs bdb 4.3.29 and a db43 port which installs exactly the same version. Now I'm asking if we can either a) remove db4 completely and upgrade ports depending on it to a specific version db4[1-6] or b) make db4 some sort of meta port depending on the latest version of db4x only without intalling anything. What do you think? This affects 14 ports which depend on db4: databases/libgda3 devel/poedit gnome/libgda lang/prothon mail/exim mail/isync mail/mutt-devel mail/spamprobe net/netatalk ruby/rb-bdb ruby/rb-bdb science/xastir sysutils/cfengine www/redland We should resolve this and don't have two ports installing the same thing. Kindly Regards, Rainer
