Right, we only have access to an i386 Mac OS X platform, and although we could 
use that to build
an x86_64 binary, I don't think we could test it.

You cd #1 only had the first 8 lines of the configure output, but I'll assume it
all looked good.

The ".la" extension identifies a text file created by GNU libtool, a tool that 
hides all the
complexity of making and using shared libraries on different platforms.

The missing routines are in the curl library, used to support the OPeNDAP 
client features
of the new netCDF library.  These features permit you to open and read from 
URLs of data
on remote DAP servers, as well as local netCDF files.  If you don't need this 
capability,
you can build without it by specifying the configure flag --disable-dap.  
However, you may
find this useful, in which case you need to add "-lcurl" to your link line in 
the Makefile.

The curl utlity and libcurl already come with Mac OS X, so you don't have to 
build and 
install them separately.

Because "make install" ran successfully, you now also have a utility program 
named "nc-config"
in the same directory as the new ncgen and ncdump utilities.  You can see what 
the library
flags should look like, including the -lcurl option, by invoking "nc-config 
--libs".
