[ncl-install] Status of NCL under MacOS 10.6 (64-bit)

[guangshan chen]

Hi Mary,

Yes, gcc-4.2 is the default 64-bit compiler on Snow Leopard. But It does not include gfortran. So If one wants to use gfortran compiler, he/she have to install
gfortran by himself/herself. 

As I posted early, some versions gcc (version >= 4.2) have problems. I tried gcc-4.4 installed by fink and gcc-4.3 installed by macports. Both of them are fine.

I have removed the cflags wiht "-arch".

Now It seems some parameters relation to JPEG are needed change. I will try to see.

I think this is the heart of the issue: HDF4 is not expecting the MacOS build to be on a 64-bit system, so it tries to treat the configuration as if it's a 32-bit one. This causes conflicting information during the "configure" phase.
