After bought a fresh new MacMini with Snow Leopard preinstalled, i decided to switch my old ns2 build to the new operating system.

Here there's the new precompiled package working under 10.5 (Leopard) and 10.6 (Snow Leopard).

Be sure to have the Xcode 10.5 SDKs frameworks and X11 already installed, before to proceed with the installations.

Happy simulations!
