To help people get started who don't want to compile the latest source code,
here is a compiled version of the desktop hosts for MOAI 1.5.2:

https://github.com/moai/moai-dev/releases/tag/Version-1.5.2-binary-desktop

Includes:
  • OSX SDL host
  • Linux SDL host
  • Windows SDL host (MinGW)

With all optional modules enabled (including LuaJIT).  People have been asking for the desktop binaries to quickly start prototyping or to play with the samples.  Halfnelson has generously built and released these on github.  A binary SDK release will follow.
