我尝试在 FreeBSD 8.0 上安装 pecl-event,但出现错误:
# pecl install event
Failed to download pecl/event within preferred state "stable", latest release is version 0.9.1, stability "beta", use "channel://pecl.php.net/event-0.9.1" to install

Make sure that you run '/usr/local/bin/phpize' in the top level source directory of the module

我做错了什么?如何安装它?
