axodraw4j.sty is not installed by this dmg.
You have to download and install it separately.
The Mac disc image was built on an Intel based MacBook Pro running OSX 10.5.5 (Leopard), and tested on OSX 10.4.11 (Panter) and PowerPC based Macs. NOTE that no java check is done, the dmg will install fine without java, but the program won't run. NOTE also that the program will run perfectly well on the Mac Java installation that is installed by default.
After downloading the .dmg file, double-click it. This will launch the self-extracting mechanism and put the JaxoDraw Application bundle on your desktop. You may then move it to the Applications folder and execute the program by double clicking the icon.
