Description:
------------
because ubuntu doesnt have PDO packages, it is necessary to 
install via pecl...

PHP_PDO_SHARED=1 pecl install pdo
PHP_PDO_SHARED=1 pecl install pdo_sqlite

cf. http://www.pecl.php.net/bugs/bug.php?id=6117

but then i get segfaults as well..

Expected result:
----------------
[Mon Jan 08 17:18:32 2007] [notice] child pid 12360 exit 
signal Segmentation fault (11), possible coredump in /tmp/
apache2-gdb-dump
