Compile Verisign PayflowPro

Releases of PHP newer than 5.0.5 removed pfpro extension, but if you are in the situation where you must get pfpro to work with PHP 5.2.1:

wget http://kdoan.dyndns.org/docs/pfpro-pecl.tar.gz
tar -xvzf pfpro-pecl.tar.gz
cd pfpro
/usr/local/bin/phpize
./configure --with-pfpro=shared,/usr/local/verisign/payflowpro/linuxrh9/lib
make
make install

This assume that you've download the SDK from Verisign and extract it to /usr/local/verisign
