Comment (by markd at macports.org):

 <<  I have no objection to MacPorts being compiled with readline support

 It has been turned off by default because it is only used in MP
 interactive mode -a seldom used option.  So your non-objection is mute.
 If you want to know the reasons why readline causes so much trouble for
 MP, ask the MP developer list or search the list archives.  But I think
 you are simply wrong about how gcc searches for stuff.  We turned it off
 because of all the "oh man it's so easy to avoid /usr/../readline
 problems" assertions over time; yet actually doing it goes way beyond MP
 (gcc issues I think) and I don't believe anyone ever came up with a way
 that would work.  But as I said, if you want to argue for the ease of a
 hypothetical solution, look at the macports-dev archives first and bring
 the discussion to the list because this has all been discussed before at
 length.  But as I said, it has been turned off and probably few (if any)
 will miss MP interactive mode.
