 To build the developers sources in one's own way, or if MacPorts' version is
 outdated, a custom port file can be added.  This requires setting up a local
 port file repository (link below).

 2.4.2 Building for Active Development of Octave
 -----------------------------------------------
 
-To satisfy Octave's dependencies, first install the octave-devel port.
-
-    sudo port selfupdate
-    sudo port install octave-devel
+To satisfy most of Octave's dependencies, first install the octave-devel port.
 
-Next run octave to determine the configure options needed to build Octave
-using MacPorts.  At Octave's prompt type the command below and make note of
-the result, ${config_opts}.
-
-    octave:1> octave_config_info.config_opts
+  sudo port selfupdate
+  sudo port install octave-devel
 
 Now uninstall the Octave port.
 
-    sudo port deactivate octave-devel
+  sudo port deactivate octave-devel
+
+This will remove Octave and leave its dependencies in place. Some additional
+dependencies may be needed.
+
+  sudo port install epstools epstoedit transfig
+
+Octave may now be built from a local mercurial archive by typing the commands
+below (these assume gcc-4.4 is installed by macports).
 
-This will remove Octave and leave its dependencies in place.  Now Octave may
-be built from the local mercurial archive by typing the commands below, where
-the configure options mentioned above are substituted for the parameter

-then ./autogen.sh must be run prior to ./configure.
