title: Change the PATH_t3lib in extensions for TYPO3 6.2
body: <p>I have an extension for TYPO3 that don't work any more after Updating the TYPO3 Version to 6.2. The log said that he don't find the <code>PATH_t3lib.'class.t3lib_svbase.php'</code>. After some research I find out that the PATH_t3lib Variable don't exist any more in TYPO3 6.2. 
  Now I have the line <code>require_once(PATH_t3lib.'class.t3lib_svbase.php');</code> that returned the error. Is there a possibility that I can simple change the require_once with the new path to the file (where ever it is) or a different simple way to solve the problem?</p>
