intel-mac binary 32 or 64 bit?

I'm running the latest ncl binary for the intel-mac (downloaded
ncl_ncarg-5.1.1.MacOS_i386_9.7.0.tar from ESG),
and I'm unable to allocate more than 3.5GB before getting a malloc
error. I was allocating 200mb variables to see where
the limit was.

> ncl(46785) malloc: *** mmap(size=200003584) failed (error code=12)
> *** error: can't allocate region
> *** set a breakpoint in malloc_error_break to debug
> fatal:NclMalloc Failed:[errno=12]
> fatal:New: could not create new array:[errno=12]

So it appears this binary is 32-bit instead of 64. Is this the case
or is there something else wrong? If so, is it possible to make a 64-
bit binary?

I'm using mac OS X 10.58 on and intel-mac with 8GB memory.

Thanks,
