Looks like you are having trouble installing the ffi gem ( blinky depends on libusb which in turn depends on ffi)
It is pretty hard to see what the problem might be from that error message. If you take a look it suggests that you might find better details in the "console.log" file.
Take a look in there and see if it is of more help, or perhaps the authors of ffi might be able to help more: https://github.com/ffi/ffi
Just a hunch - have you installed the Apple Developer Tools? If you haven't you probably don't have a c compiler..
Very excited to use this! I have the latest command-line tools and brew is updated. Libusb installs no problem. When I 'sudo gem install blinky' on 10.8.3 it fails, please help. Install ends with: "Configuring libffi for i386 configure: WARNING: if you wanted to set the --build type, don't use --host. If a cross compiler is detected then cross compile mode will be used configure: error: in
/Library/Ruby/Gems/1.8/gems/ffi-1.8.1/ext/ffi_c/libffi-i386': configure: error: C compiler cannot create executables" Seeconfig.log' for more details make[1]: *\ No targets specified and no makefile found. Stop.
