If evaluating (gnutls-available-p) returns t, then you are using the
gnutls library (if the function is undefined then your Emacs is not
compiled with libgnutls support). And if you hit bug 22929/23225/23503
then you might notice by seeing that https doesn't work :(
I don't run OSX (Ted was the one mentioning "pre-built binary
packages"), so I can't say much more than that.
