I\'ve built from source php + php-fpm + nginx few times.
I\'m used to keep everything inside /usr/local
/usr/local
Hovewer php-fpm config file php-fp
php-fp
actually the real reason is you used the old TARed php source code, you should RM the old TARed php source one and re-Tar xvf php-version.tar.gz, lastly, configure it and so on. you can try it if you don't believe it~
