buildconf: You need autoconf 2.59 or lower to build this version of PHP. You are currently trying to use 2.63 Most distros have separate autoconf 2.13 or 2.59 packages. On Debian/Ubuntu both autoconf2.13 and autoconf2.59 packages exist. Install autoconf2.13 and set the PHP_AUTOCONF env var to autoconf2.13 and try again.
a reported solution is to type:
yum install autoconf213 export PHP_AUTOCONF=/usr/bin/autoconf-2.13
and then try the php build again.
