Hi to all,
the problem is solved. First you must read my first post and the solution is to make a link with the library libbfd-2.15.90.0.3.so to libbfd-2.15.so in /usr/lib directory, but, and here is the important point, you must use the option "f" when you link the library.
So you must use: ln -sf /usr/lib/libbfd-2.15.90.0.3.so /usr/lib/libbfd-2.15.so
Now it works perfectly.
Thank you very much to Z Z at providence.usa.com for emailing me with the explanation.
