That does work for me, and for quite a few other people.

All of these missing symbols seem to be from OpenSSL, which I don't
understand because your configure command didn't say --with-openssl.
Are you sure that's actually the full set of options you're using?
Maybe you have a stale autoconf cache you need to clean out?

If you are using --with-openssl, I wonder which OpenSSL you are
using. Apple deprecated their system-library version of that
long ago, and perhaps it's finally gone in Tahoe. Most of us
use Homebrew or MacPorts to install a version of the openssl
libraries that we can use with PG. If you are trying to do it
like that, I think the problem is that you're missing --with-includes
and --with-libs configure options to point at that installation.
For instance, I use

--with-includes=/opt/local/include --with-libs=/opt/local/lib

to build with MacPorts' openssl.
