I am trying to compile Verising Payflowpro module for PHP/Apache, here are the commands I used:

copied libpfpro.so and pfpro.h to the same directory /usr/local/verisign/payflowpro/solaris/lib

config statement for php:
=============================================
./configure --with-mysql --with-apache=../apache-1.3.19 --enable-track-vars --with-pfpro=/usr/local/verisign/payflowpro/solaris/lib

make
make install
=============================================

changed directory to apache-1.3.19 and ran the following config:
============================================
./configure --activate-module=src/modules/php4/libphp4.a
make
============================================

make fails with the following errors:
============================================
