PECL help

I'm trying to install the extension runkit on my shared server. I successfully installed a local copy of PEAR via the instructions at http://pear.php.net/manual/en/installation.shared.php. Here is the resulting configuration: Configuration (channel pear.php.net): =====================================

However when I try to install runit, I get an error: bash-3.00$ pecl install runkit-beta downloading runkit-0.9.tgz ... Could not download from "http://pecl.php.net/get/runkit-0.9.tgz", cannot download "pecl/runkit" (could not open /tmp/pear/cache/runkit-0.9.tgz for writing) Error: cannot download "pecl/runkit" The directory /tmp/pear is owned by root, so I can't make changes to it. If I try to change the temp-dir to something that works, I get another error: bash-3.00$ pear config-set temp-dir ~/tmp config-set (temp-dir, /home/maximumr/tmp, user) failed, channel pear.php.net How can I make this work?
