When I install wordpress plugins, I often get the error
Warning: include_once() [function.include]: Failed opening '/usr/share/wordpress/wp-content/plugins/twitter-for-wordpress/' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in /usr/share/wordpress/wp-settings.php on line 473
I have Pear installed, but Ubuntu clearly didn't put it in the expected place. There must be an alias that can fix this, does anyone know what it is?
