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
