TYPO3 Core

Whenn I try to install ADOdb 4.71.1 under typo3 4.0beta3 I always get the following error:
Dependency Error:
Extension "php" was not available in the system. Please import it from the TYPO3 Extension Repository.
Extension "typo3" was not available in the system. Please import it from the TYPO3 Extension Repository.

Try to install ADOdb.

I think the new ext_emconf - format is the problem. In this file of ADOdb stands:
'constraints' => array(
'depends' => array(
'php' => '',
'typo3' => '',
),
'conflicts' => array(
),
),

and in typo3/mod/tools/em/index.php by the line 3377 (if($depK 'php' && $depV)) the var $depV is empty and on line 3389 (elseif($depK 'typo3' && $depV)) the var $depV is also empty so line 3400 (elseif (!t3lib_extMgm::isLoaded($depK))) comes to execution, which produces the above names error.
