At the very last I managed to correctly install it thanks to your
suggestions. I truly don't remember how, but I think I had to run nettle
installation two times before it worked correctly
Best regards, Vittorio

Ok, then the flags I gave you aren't quite right. You have to follow
the
suggestion to look in config.log to see what went wrong. But I think I
made a typo, it should probably be "-rpath", not "rpath".
If this is confusing, you may also want to read up on how the runtime
linker locates libraries.
Or as a quick test to see if this really is the problem, try setting
LD_LIBRARY_PATH, and run
LD_LIBRARY_PATH=.lib:/usr/local/lib ldd testsuite/ecc-mul-g-test
LD_LIBRARY_PATH=.lib:/usr/local/lib ./testsuite/ecc-mul-g-test
zaamus@zaamuspc:~/Dependencies/nettle-2.7.1$
LD_LIBRARY_PATH=.lib:/usr/local/lib ldd testsuite/ecc-mul-g-test
linux-gate.so.1 => (0x40022000)
libhogweed.so.2 => .lib/libhogweed.so.2 (0x40026000)
libnettle.so.4 => .lib/libnettle.so.4 (0x40054000)
libgmp.so.10 => /usr/local/lib/libgmp.so.10 (0x40087000)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0x40119000)
/lib/ld-linux.so.2 (0x40000000)
zaamus@zaamuspc:~/Dependencies/nettle-2.7.1$
LD_LIBRARY_PATH=.lib:/usr/local/lib ./testsuite/ecc-mul-g-test
zaamus@zaamuspc:~/Dependencies/nettle-2.7.1$
This indicates that your nettle build works fine, if you only get it to
link with the right libgmp.so file at runtime
(/usr/local/lib/libgmp.so.10 above).
