[netCDF #FCB-421026]: Biulding netcdf librairies.....problems...advices needed...

Yes, I think you are trying to run "make install" as an ordinary user, who 
doesn't
have the necessary permissions for installing in a system directory, such as
/usr/local/lib or /usr/local/include.  If you have "sudo" permissions, try 
running

  sudo make install

which will ask for your password.  If you aren't set up as a "sudo" user, 
you'll either
have to login as "root" to run the make install command, or install netCDF in a
directory where you have the necessary permissions, such as your home 
directory.  To
specify an alternate installation location, instead of the default 
"/usr/local", 
use the --prefix= option to the configure script after running "make clean" but
before running "make check" and "make install".

You need to have built and installed the netCDF 4.2.1.1 C library before
trying to build and install the netCDF-4.2 Fortran library, as described
here:

  http://www.unidata.ucar.edu/netcdf/docs/netcdf-fortran-install.html

No, that's not necessary or advisable.  You can use netCDF 4.2.1.1 with any
program that worked with netCDF-3, as it's backward compatible.  And you
built without the HDF5 library (or maybe with the --disable-netcdf-4
configure option), so what you have is essentially netCDF-3 with some bug
fixes included since the old netcdf-3.6.3 release.
