How about a compromise?

Change it to USE_BDB?=41+ and have a pre-everything target that looks  
at the computed BDB_VER, and pops up a "you might hose yourself"  
message if it's something other than 41?

I understand the backwards-compat issues, but it seems a little odd to  
have a specific BDB dependency for this when most other BDB-using  
ports can at least have the option to try alternatives.
