Okay, I updated my Ports repository on my FreeBSD vm, and I'm seeing
this same sort of failure failure with gcc 4.2.1 and gcrypt 1.5.2 (wow -
Fedora rawhide still only ships with gcrypt 1.5.1).

The sad part is that we aren't even using the deprecated symbols - their
mere inclusion in the installed header is provoking the problems. It
looks like newer gcc is a bit more tolerant (that is, this is a
shortcoming of FreeBSD's use of an older compiler).

I'm trying to come up with the best workaround (perhaps disabling
-Wdeprecated-declarations if gcrypt.h exists but provokes compiler
warnings).
