Ubuntu 14.04 has two GnuTLS versions available, 2.8.x and 3.x. Support
for the former was dropped in master. If RSA decryption support is
important to you, install libgnutls28-dev for the 3.x version.

Of course the build should not fail if the GnUTLS 3.x version is
missing, this should fix the build issue without GnuTLS:
