In MySQL 5.5, the InnoDB Plugin is the default version and it's compiled in.
In this case, the plugin cannot be uninstalled and we get error when trying
to do so:
mysql> uninstall plugin innodb;
ERROR 1305 (42000): PLUGIN innodb does not exist
But the error message is misleading. The plugin does exist, it just cannot
be installed because it's not dynamically loaded.
