As with all dependency validation, true is returned on success, PEAR_Error on failure for required dependencies (and the PEAR installer dependency is required). If the soft, force or ignore-errors options are specified, an array containing the error message will be returned instead.
This method retrieves the list of packages to be uninstalled from the PEAR_Installer object, and makes sure no dependencies with existing packages would be broken if the current package were to be uninstalled.
