[MacRuby-devel] [MacRuby][0.5] Which version of rake version to use?

Hi, I was wondering, which version of rake should one use to build and run the specs/benchmarks with? I ask this questions because my default points to /opt/local/bin/rake which is the version that's parts of my MacPorts install of Ruby 1.9.1p129. Also, I noticed that there's a version called macrake which generates the following error on execution: Segementation fault -Conrad
