PHP 4.3.1 make error

Hi, just trying to install PHP 4.3.1 as per the article (https://www.afp548.com/Articles/Jaguar/php431.html), everything went well until I got to the PHP make command - then I got the following at the end of the terminals feedback from make ld: /usr/local/pgsql/lib/libpq.a(fe-secure.o) illegal reference to symbol: _DH_size defined in indirectly referenced dynamic library /usr/lib/libcrypto.0.9.dylib ld: /usr/local/pgsql/lib/libpq.a(fe-secure.o) illegal reference to symbol: _TLSv1_method defined in indirectly referenced dynamic library /usr/lib/libssl.0.9.dylib make: *** [libs/libphp4.bundle] Error 1 any idea whats wrong here? I can send the entire terminal output of make, if it helps - I need 4.3.1 on a working server and so am testing it on a development server (same server software - 10.2.6). Only thing I have added to the PHP configure script is --with-pgsql which I need Any help greatfully received.
