First of all, thanks for your patience

I am sure I have installed gmp6.0.0: I have done it right before
trying to install nettle.
Using apt-get, or compiling from source (and then typically installing
under /usr/local)?
However, this is what I get with your tests
zaamus@zaamuspc:/usr/local/itt/idl70/lib$ dpkg -S

This shows that the version installed under /usr/lib is *not* version
6.0. So if you have installed gmp-6, it's located somewhere else on the
system. I'm going to assume it's under /usr/local.
I will check... for now I will simply send you the results of your check
You need to tweak the invocation of nettle's configure script to pick
it
up (or, alternatively, edit /etc/ld.so.conf to include /usr/local/lib
by
default, and run ldconfig, but that might have undesirable side
effects).
What probably happened, is that you got header files for gmp-6 in
/usr/local/include, and gcc searches that directory by default. And you
got the corresponding library installed under /usr/local/lib, which
might be searched by default during link time, but *not* during
runtime.
Try rerunning nettle's ./configure as
./configure LDFLAGS="-L/usr/local/lib -Wl,rpath,/usr/local/lib"

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$
