It's good to hear that you figured out how to compile and link using 
libtool.

The libtool utility is intended for use by package developers to make
it easier to build shared libraries on different platforms, given that
there is no standard way to create shared libraries.  It needs to run
dynamically linked libraries before the libraries have been installed,
so it must use arguments that users wouldn't typically have to use.

That's why we recommend running "make install" after you have run
"make check".  After installing the library, it is no longer necessary
to use libtool, and compilation and linking is simplified whether you
are using static or shared libraries.  We also provide the "nc-config"
tool to make it easier to compile and link netCDF applications, and it
assumes "make install" has been run.

I hope this makes it clearer why we don't document or offer guidance on
using libtool for compiling and linking user applications.  However, now
that this response is in our searchable support archives, it may help 
other users decide whether and when to use libtool versus "make install"
and nc-config.
