If you can figure out how to detect and configure around the OSX
defective readline library, that would be great.  So far, I have not
seen a way to do this.  It claims to be readline, but it isn't.

I have been told that the OSX "libreadline" library is actually a disguised
version of the BSD libedit.  Since as of recently gnuplot can use libedit
instead of libreadline, the best solution would be (if it works) would be
to force the --with-readline=bsd on OSX configurations.  Unfortunately,
I do not know if OSX also provides an un-wrapped libedit that doesn't
pretend to be libreadline.  Could you please try 
  ./configure --with-readline=bsd
and see how it works?
