this might depend on the new mode CLI which is not BE.

my working solution:
	$TCE = t3lib_div::makeInstance('t3lib_TCEmain');
	// this seems to initalized a BE-User
	$TCE->start(Array(),Array());
	// so this line does not throw an error any more
	$TCE->clear_cache('tt_news',$oneRecordId);

with this I simulated one record-change
and in combination with the Page-TSconfig:
	TCEMAIN.clearCacheCmd = 40
I get a cleared cache.
