The inbuilt mysql stops php from compiling. Build works if '--without-msql' is used in the configure stage.

'./configure' '--with-apxs=/usr/local/apache/bin/apxs' '--with-pgsql=/usr/local/pgsql' '--with-curl=/usr/local/curl' '--with-curlwrappers' '--enable-mbstring' '--disable-cgi' '--enable-sockets' '--with-openssl=/usr/local/ssl'
