 4. Make sure that java, javac, jar, gcc are in your path.
    Run the configuration script.

        > ./configure

    The configuration script has the following options:

        --prefix=<path>
            The root path where the installation goes. For example,
             to install the libraries into /usr/local/jmagick/lib,
             use --prefix=/usr/local/jmagick

        --with-magick-home=<path>
            Use this if your have ImageMagick install in non-standard places.
            E.g. ./configure --with-magick-home=/usr/local/ImageMagick

        --with-java-home=<path>
            Use this to specify where your JDK is installed. This is NOT
            necessary if you have the JAVA_HOME environment set.
            E.g. ./configure --with-java-home=/usr/local/java

        --with-java-includes=<path>
            Use this to specify a Java include directory.

        --with-jikes
            If you wish to use the IBM Jikes compiler instead

        --enable-diagnostic
            If you want verbose messages. Only a few messages are available
            at the moment.

        --with-javadoc-dir=<path>
            To specify a directory path for the javadoc.

 5. Then make everything.
