Comment(by michelle.lynn.gill@…):

 My apologies for reviving an old thread, but I figured out the problem in
 the event that others report a similar issue...

 The file readline.pth imports "readline_path" which, in turn, loads
 readline only if the directory
 "/Volumes/Files/macports/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /lib-dynload" is found in sys.path.

 Unfortunately, I had the variable $PYTHONHOME set to
 "/Volumes/Files/macports/Library/Frameworks/Python.framework/Versions/Current",
 thus my analogous sys.path entry is
 "/Volumes/Files/macports/Library/Frameworks/Python.framework/Versions/Current/lib/python2.7
 /lib-dynload". These two strings never match and, thus, readline was never
 being loaded for me.

 It's not an issue for me to change my PYTHONHOME variable, but maybe
 there's a more robust change that should be made to the readline-
 associated files? Regardless, hopefully this will help in the future if
 the problem arises again. Thanks!!
