I've been trying to compile 0.5 from SVN with no luck. I installed LLVM revision 72741 as outlined in the readme but when I ran MacRuby's rake file I got the following error:
../../miniruby -I../.. -I../../lib -r rbconfig -e "RbConfig::CONFIG['libdir'] = '../..'; require './extconf.rb'" Assertion failed: (castIsValid(getOpcode(), S, Ty) && "Illegal BitCast"), function BitCastInst, file Instructions.cpp, line 2493.
Thinking my environment might be the problem, I installed a fresh copy of Leopard and reinstalled LLVM. I still get the same error message. Further investigation reveals that the problem occurs when rbconfig is required by miniruby in line 325 of builder.rake. It throws the error when when it encounters the "==" in "RUBY_VERSION == "1.9.0"" at the top of rbconfig.rb. I encounter similar problems (and the same error message) concatenating strings (-e "'string' + 'string'") with miniruby. Both experiments share a similar gdb backtrace:

Is there any way I can get this edge release working? I'm on a MacBook Pro with a 2.16GHz Core Duo running 10.5.7. Thank you, Max Hawkins
