[netCDF #MLU-486882]: NetCDF must be built with netCDF-4 enabled

Your CPPFLAGS isn't getting passed into the configure script, because its 
compile
line (in config.log) is

  configure:15660: gcc -c -g -O2  conftest.c >&5

instead of 

  configure:15660: gcc -c -g -O2 -I /usr/local/include conftest.c >&5

I suspect either you're using a shell that uses a different syntax for setting
environment variables (for example csh uses "setenv CPPFLAGS ..." or you're not
exporting the environment variable after you set it, as in

   CPPFLAGS="-I /usr/local/netcdf/include"
   export CPPFLAGS

or just

   export CPPFLAGS="-I /usr/local/netcdf/include"

You can also use the environment variables as just arguments to the configure 
script, as in:

   ./configure CPPFLAGS="-I /usr/local/netcdf/include" LDFLAGS=...

If it still won't work, another possibility is installing netCDF from one of
the package management systems, such as fink or MacPorts.
