I just ran into the same issue on a hosting service I used before without problems.
From the error log
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/sqlite.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/sqlite.so: undefined symbol: third_arg_force_ref in Unknown on line 0
