When you got your Mac, did you only have "bash", and no "csh" or "tcsh"? I tried googling on this topic, but it isn't clear to me the best way to get these shells for your Mac.

I think you should be able to use the NCL that you have. It's confusing, because the version you have was built on a system that claims it is "i686", but it was built in 64-bit mode (using the -m64 option with gcc/gfortran). For this reason I believe it should work fine under x86_64. I'm hoping to get access to a Mac that reports x86_64 so I can test this myself.

You can try, but I would recommend trying to get what you have to work first. Building from source is not trivial. However, I will be happy to help you with this.
