I can't reproduce this, the build succeeds for me, and ldd shows that
libcurl is indeed linked to libgnutls and not libssl.
What does configure say about libnettle? For me it says:

checking for pkg-config... /bin/pkg-config
checking for gnutls options with pkg-config... found
checking for gnutls_check_version in -lgnutls... yes
configure: detected GnuTLS version 3.0.4
checking for nettle_MD5Init in -lgnutls... no
checking for gcry_control in -lgnutls... no
checking for nettle_MD5Init in -lnettle... yes
checking for gnutls_srp_verifier in -lgnutls... yes

Also, have a look at config.log to see what happened.
It looks to me as though it's not linking to libnettle. Try configuring
it with:

LIBS="-lnettle" ./configure --prefix=/usr --without-ssl --with-gnutls
