 While that might be true, serf does have a library dependency on bdb when
 built against an apr-util that also has a library dependency on bdb (which
 is the default).

 It should probably declare a dependency on bdb (and have a +no_bdb variant
 that just removes that dependency) so that MacPorts warns the end user
 that removing bdb will break serf.

 true, I'm sure a patch to base would be welcome ;-)
