Here are instructions for building rw05 on Mac OS X the way that I did it.

1. Make sure Xcode and X11 are installed.
=========================================

OS 10.4 or later should come with Xcode and X11 pre-installed or on the DVD.
Make sure they are installed. 
You may also wish to update them. Go to 
http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wa/downloads
to download a newer version and any updates. If you don't have an
Apple ID, you can create one by registering for free at
http://developer.apple.com/programs/start/register/create.php


2. Install tools and libraries.
===============================

You can do this in one of at least two ways:

------------------
A. USING MACPORTS:
------------------

Download and install MacPorts. You can get it, for example, from
http://svn.macports.org/repository/macports/downloads/
or use the instructions at
http://trac.macports.org/wiki/InstallingMacPorts

You may need to install the java development headers from the Apple
Developer site:
https://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wa/getSoftware?bundleID=20719
If you don't have an Apple ID, you can create one for free at
http://developer.apple.com/programs/start/register/create.php

Update MacPorts and its repository lists by typing
    sudo port selfupdate

Use MacPorts to install the following packages:
[ readline ] - may already be on system in MacOSX10.*.sdk
  lesstif     (required for xm* versions of gf3, gls, escl8r, etc)
  gtk2        (required for gtk* versions of gls, escl8r, etc)

You would normally do this from the terminal, by typing 
     sudo port install <package-name>
for each <package-name> above. Other dependent packages will also be 
installed automatically, and the process will take some time.


--------------
B. USING FINK:
--------------

Download and install the Fink package-management software by following
instructions at
http://www.finkproject.org/doc/users-guide/install.php
 
Start the Fink application. From the list of applications, choose the
following packages to install:
[ readline ] - may already be on system in MacOSX10.*.sdk
  lesstif     (required for xm* versions of gf3, gls, escl8r, etc)
  gtk2        (required for gtk* versions of gls, escl8r, etc)


3. Build RadWare
================

Download the latest version of Radware. The build and install process
is similar to that for other Linux/Unix systems, so refer to the README.

Use Makefile.macosx as the starting point for your Makefile:
    cd rw05/src
    cp Makefile.macosx Makefile

You may need to edit this Makefile to match your system.
Again, please refer to the Linux/Unix README for other comments.
Then build rw05 with the command
    make

You can run the programs directly from the rw05/src directory, or
optionally install them in a different place. To do the install,
edit the Makefile so that the install path and user/group details are
appropriate for your system. Then run
    make install

For instructions on setting things up to run the programs easily,
please look at sections 4) through 7) of the Linux/Unix README.
