Hi Nikos,

I believe it was a distribution's version (Ubuntu). I suspect it was 2.8.5, but don't know for sure.

I performed the process of installing Nettle and GnuTLS a second time. Instead of make bootstrap (per http://git.savannah.gnu.org/cgit/gnutls.git/tree/README-alpha), I used configure this time around. gnutls-cli-debug now runs and claims version 2.11.5.

Good question. I managed to shoot myself out of the water since reporting and your subsequent question.

Below are the effects of a 'configure/make/make install' cycle from the bleeding edge gear fetched with git.

$ gnutls-cli-debug --version
gnutls-cli-debug: /usr/lib/libgnutls.so.26: version `GNUTLS_2_12' not found (required by gnutls-cli-debug)

Is this the output of 2.11.x gnutls-cli?
