installing pear --without-pear

[Ofer Inbar <cos@xxxxxxxxx>]

http://pear.php.net/manual/en/installation.php
documents two options for installing the PEAR manager:
 1. As part of PHP's make, as long as you don't do --without-pear
 2. go-pear.php, which is interactive (and apparently "provisional")

Is there a supported *noninteractive* way to install PEAR after a
PHP 5.2.* make that was configured --without-pear ?
