>From my distro config:

  # gmp 4.2.1 is the last version released as LGPLv2
  # nettle 2.7.1 is the last version released as LGPLv2
  # gnutls 3.3.x is the last branch which supports nettle 2.7.1
  PREFERRED_VERSION_gmp = "4.2.1"
  PREFERRED_VERSION_nettle = "2.7.1"
  PREFERRED_VERSION_gnutls = "3.3.%"
