Hey All,This is my first post to this list so I should introduce myself. My name is Steven Canfield I've just graduated from a Master's program in Computer Science and am doing iPhone development as my day job. I've found the MacRuby project intriguing since it was announced (and helpful in my last semester) so I'm ready to start giving back. I've checked out the experimental branch and am trying to work through some of the spec tests from http://github.com/alloy/mr-experimental/blob/master/spec/README.rdoc However, I can't get MacRuby to actually build. Right now I am using revision 2088 of the experimental branch. When I try to build (using 'rake'), I get Assertion failed: (ee != NULL), function RoxorCore, file vm.cpp, line 208. rake aborted! Command failed with status (): [../../miniruby -I../.. -I../../lib -r rbco...] Looking into that it's clearly something with LLVM. I figure it's probably the specific LLVM version I am using, but I've tried both 72741 (mentioned in the Readme.rdoc file) and trunk (77106). I get the same error with each. I'm doing this on 10.6 so if there are special instructions for that you could reply to me off list. Thanks for any guidance, -Steve
