[TYPO3-english] PHP 5.3: unable to access simplepie.inc

[Claudio Strizzolo]

Hi all,
since upgrading from PHP 5.2 to 5.3 on my Typo3 4.3.2 server, a lot of 
warning messages such as the following get appended to the httpd log 
file, always in pairs:

[Tue Mar 30 15:05:46 2010] [error] [client xxxxx] PHP Warning:  
spl_autoload() [<a href='function.spl-autoload'>function.spl-autoload</
a>]: Unable to access simplepie.inc in /.../typo3_src-4.3.2/t3lib/
class.t3lib_autoloader.php on line 110
[Tue Mar 30 15:05:46 2010] [error] [client xxxxx] PHP Warning:

a>]: Unable to access simplepie.php in /.../typo3_src-4.3.2/t3lib/
class.t3lib_autoloader.php on line 110

Any hints?
Thanks in advance,

Claudio
