PHP/Postgresql problem

I am trying to get PHP to work with an instance of postgresql on a server. There is already one, 'proprietary' postgresql running with its own user, own group and own (not default) port. The postgresql I am installing will be used for several database projects. following are my config/makes and the results: Postgres (7.3.5) configures, compiles and installs cleanly with: ./configure --enable-odbc --enable-tcl --enable-locale --with-python --with- perl --with-readline make; make install At which point I can create users and databases and connect to them with the command-line tools. PHP configures and compiles cleanly with: ./configure --with-apxs=/usr/local/apache/bin/apxs --with-mysql --with- pgsql=/usr/local/pgsql --with-gettext --with-ldap --without-imap --enable- sigchild --enable-force-cgi-redirect make However make test (or make install and attempt to use it) yield the follow flow of messages: PHP Warning: Function registration failed - duplicate name - pg_connect in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - pg_pconnect in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - pg_close in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - pg_connection_status in Unknown on line 0
