libreadline.a is the statically-linked library. Are you sure there  
aren't also any dynamically-linked libraries of readline in /usr/ 
local/lib? Their names would be libreadline.*.dylib.

You'll also want to check for and remove any readline includes in / 
usr/local/include.

Others have encountered this problem before; see:

I guess we should write a FAQ entry about it. Anyone wanna do that?

Devs: I think this problem occurs because MacPorts needs a newer  
version of readline than the one you have in /usr/local. Couldn't we  
add a check to ./configure to make sure the correct version of  
readline is available, and issue a sensible error message if not,  
rather than failing with this unfortunate undefined symbols error  
later on? Or, couldn't we instruct configure never to look for  
anything in /usr/local? I believe the latter has been suggested  
before but I don't remember the outcome.
