MacRuby 0.5 beta 1

MacRuby is now in beta:

The new MacRuby 0.5 runtime is built upon LLVM, a compiler infrastructure also sponsored by Apple. Thanks to LLVM, MacRuby is able to transform the Ruby abstract syntax tree (AST) from the parser directly into highly optimized machine code. MacRuby supports both Just in Time (JIT) and Ahead of Time (AOT) compilation. The JIT mode will compile down the code at runtime, and the AOT mode will allow you to save on disk the compilation result. AOT compilation makes MacRuby a true Ruby compiler.

Very cool. Compatibility with RubySpec is much lower than I would have expected, though.
