Comment(by christoperyeoh@…):

 The results follow.  So I guess I installed the 64-bit version of readline
 in correctly?

 > % port installed readline
 The following ports are currently installed:
   readline @6.1.002_0 (active)

 > % file /opt/local/lib/libreadline.dylib
 /opt/local/lib/libreadline.dylib: Mach-O 64-bit dynamically linked shared
 library x86_64
