Moin Alexander,

Basically this is at the end what I had to do in retrospective, i.e., to 
recompile Octave and specifying the path to the Unidata netcdf library.

I need the Unidata netcdf for another package (Climate Data Operators of 
the Max Planck Institute for Meteorology), as far as I know these 
operators only work with the unidata library.

Thanks for all these tips relating the compilation and checking of what 
libraries are linked. I will consider them for the next time so that I 
can make a cleaner compilation. Have a nice weekend. Ismael.
