Dependencies of my programs on Mac OS X

Library requirements of using my engine on Mac OS X:

For OpenGL programs, X11 (may be found on Mac OS X install CD).

And you should run my programs from within X11 xterm, to use your display. Or you will have to specify your X display by command-line option explicitly, like --display=:0

This requirement will be removed if at some time I'll implement GLWindow unit using some native Mac OS X libraries. Contributions are most welcome if you're experienced with programming under Mac OS X !
libpng (may be installed by fink), if you want to be able to open any images/textures etc. stored in PNG images.
When GLWindow uses GTK backend (view3dscene compiled by default script does use GTK, "The Castle" compiled by default script doesn't use GTK): GTK and GtkGLExt are required. May be installed by fink (look for packages gtk+2, gtkglext1).
Note: Binary gtk+2 packages in fink may be too old. If you get errors on the console like
```
  dyld: Library not loaded: /sw/lib/libgtk-x11-2.0.0.dylib
  Referenced from: /xxx/view3dscene
  Reason: Incompatible library version: view3dscene requires version 601.0.0 or later, but libgtk-x11-2.0.0.dylib provides version 401.0.0
```
then try installing gtk from source packages, they have newer version (or bug fink to update binary packages more often :) ). It is not necessary to use any fink packages from unstable branch !
OpenAL for game sound (may be downloaded from Creative, see download links from openal.org downloads, newer Mac OS X has this pre-installed ?) along with vorbisfile (may be installed by fink).

For libs installed by fink, you may have to add them to your libs path by command like

  export LD_LIBRARY_PATH=/sw/lib:"$LD_LIBRARY_PATH"

before executing programs. (you can add this to your .bashrc or similar file for comfort).
