Its good to hear others are successful building on MacOS X!

I choose to install the 32bit version of Fink. Thus, my Octave is 32bit only. 
So, I won't be any help with a 64bit build, but you might look at the link 
below (64-bit R for Mac OS X)

If you still have problems, I recommend you post the detail and see if someone 
has an idea. You may also want to describe the unique gcc options on MacOS X 
... -m32 and -m64, for example.
