The proper link line that needs "-lsun" gets put in all the Makefiles when
they are generated by "configure".  I just tried this from the netcdf-232pl2
distribution on an SGI running "IRIX Release 5.2 IP20", and everything just
worked without having to manually edit any link lines or Makefiles.  Perhaps
you aren't using the "configure" script to generate the Makefiles?

If you've already got the distribution, you should first type 

   make distclean

to start over, removing all the existing generated files, including
Makefiles and object files.  This should be equivalent to getting a new copy
of the compressed tar file and unpacking it.

Next, use the "configure" script from the top-level netCDF directory to
generate Makefiles.  You may need to specify a value for the "prefix" where
you want things installed later, if the default is not acceptable.  Here's
what I used when I was testing it:

    ./configure --prefix=/home/russ/build

This resulted in the following output:

    checking for cc
    checking for ar
    checking for ranlib
    checking for fill value usage

    post processing makefile `port/Makefile'

If you get something different from invoking configure, please send it,
along with the config.status file that gets generated so we can try to
diagnose the problem.

Next, you should only have to invoke "make" with no arguments.  Following is
the output I got from 

    make

Notice the "-lsun" has been put in the Makefiles by the "configure" script
so that you shouldn't have to edit the Makefiles to get it there:

After this, if I invoke

    make test

All the tests succeed and show everything has been built satisfactorily.
Then you should only have to type 

    make install

to get things installed where you originally specified with the --prefix
argument to configure.
