gems/ruby/2.0.0/gems/nanomsg-0.2.0/ext/constants.o: Mach-O 64-bit object

gcc is building a Mach-O object on an x86_64 machine, which is related to ext/Makefile containing "arch = x86_64-darwin12.3.0" though Im not sure what the fix is.

Issue #2 was marked as a duplicate of this issue.

What operating system are you building on? How did you install Ruby (with what commands, from what source)? What version of Ruby did you install? Did you install other (binary) extensions before this one? (aka: Has the compilation process involving mkmf.rb worked once?)

[Kaspar Schiess]

I've just pushed a new version (0.3.0) that should fix this. Can you try?

[Don Park]

It looks like that fixes up the installation process, thanks!
