I got various errors trying to get Octave 3.4.0 to graph via gnuplot on Mac OS X 10.7.4, but here is how I finally got it to work:

== Install X11 ==
(Not sure if this step is needed, but I did it anyway.)

Install XQuartz-2.7.2.dmg available from
http://xquartz.macosforge.org/landing/

== Install AcquaTerm ==
Install AquaTerm1.0.1.dmg available from
http://sourceforge.net/projects/aquaterm/files/AquaTerm/

== Install readline ==
(Reference: http://bhou.wordpress.com/2011/09/13/how-to-install-gnuplot-in-mac-os-x-lion/)

Download the latest ReadLine lib source (readline-6.2)
Create a folder in any place you want to install readline lib (except /usr/local/), Example: /Users/username/Local
unzip the lib downloaded and type the command in a console:

./configure  --prefix=<the path of the folder you just created>
make install

Usually you will have an error that use -dynamiclib rather than -dynamic

You need to go into the sub folder shlib in the ReadLine source folder and edit Makefile, search -dynamic and change it to -dynamiclib

make clean
sudo make install

== Install gnuplot ==
(Reference: http://www.macresearch.org/gnuplot-aquaterm-snow-leopard-1061)

Download the latest gnuplot source from: http://sourceforge.net/projects/gnuplot/files/gnuplot/

# Setting to 32 bit as AcquaTerm doesn't have 64-bit support
export LDFLAGS=-m32
export CFLAGS=-m32
./configure --with-readline=/Users/username/local/ --without-tutorial --without-x
make 
sudo make install

== Install Octave ==
Install octave-3.4.0-i386.dmg available from 
http://s3.amazonaws.com/mlclass-resources/software/octave-3.4.0-i386.dmg

== Verify installation ==
/Applications/Octave.app/Contents/Resources/bin/octave
octave-3.4.0:1> sombrero()

(Should see a nice graph displayed)

That's all and good luck!
