どうもパーミッション絡みのようだ
対策
Config/Core.phpに以下記述
/**
 * Configure the cache used for general framework caching. Path information,
 * object listings, and translation cache files are stored with this configuration.
 */
Cache::config('_cake_core_', array(
'engine' => $engine,
'prefix' => $prefix . 'cake_core_',
'path' => CACHE . 'persistent' . DS,
'serialize' => ($engine === 'File'),
'duration' => $duration,
'mask' => 0666 // ←ここ追加
));

/**
 * Configure the cache for model and datasource caches. This cache configuration
 * is used to store schema descriptions, and table listings in connections.
 */
Cache::config('_cake_model_', array(
'engine' => $engine,
'prefix' => $prefix . 'cake_model_',
'path' => CACHE . 'models' . DS,
'serialize' => ($engine === 'File'),
'duration' => $duration,
'mask' => 0666 // ←ここ追加
));

するとOK
$ /usr/local/bin/php /path/to/cakephp/app/Console/cake.php initial_import -app /path/to/cakephp/app
