I had to figure out how to compile php on a plesk machine and actually get it to work so I took the time to document everything. This guide *should* work, I know it worked on 2 seperate machines. Aside from that do it at your own risk I am not so fond of plesk because it does have so many issues with upgrade. If you have any trouble or dep issues please post thme here so I can work the fixes into the guide.
