I created a patch against NetHack 3.4.3 that incorporates the patch-set from nethack.alt.org, allows easy compilation and installation on OSX, and enables the --version flag.

Now that NetHack is on 3.6 (and many of the important patches have been incorporated into the main branch), I consider the project complete. If you find any issues, though, don't hesitate to let me know!
