Did you forget to link the program with the gnutls library?  You'll
need to compile it using something like this:

cc -o foo foo.c -I/path/to/gnutls/include -L/path/to/gnutls/lib -lgnutls

Alternatively, if you built GnuTLS yourself, invoke 'make' in the
doc/examples/ directory.  The examples are built when you build
GnuTLS.
