A better solution is to test for features and not version numbers.
Did you add some new externally visible API in 0.6, that the updated
GnuTLS code would need? Then check for that, using something like:
#include <stddef.h> /* opencdk <= 0.5.13 uses size_t without this include */
#include <opencdk.h>], [cdk_new_function_foobar;])
Btw, I think we should add something like what's in gnutls.h into
#define LIBGNUTLS_VERSION_MAJOR 1
#define LIBGNUTLS_VERSION_MINOR 7
#define LIBGNUTLS_VERSION_PATCH 9
This allows M4 tests to do version-based testing, if someone prefers
to use that in some situation. It should go into opencdk.h.in, and be
substituted, of course.

Sounds good! Maybe you could post the patch for easier review?

'make check'? If there are no self-tests for OpenPGP, which I guess
there aren't, write a self-test and test it with the old/new code.
See pskself.c, anonself.c etc.
