PHP Warnings keep piling after migration

After successfully migrating an installation over to another server, seems like every page load keeps outputting the following warnings into 'error_log' (different hosting providers but former and new servers are both Linux/php5)

[01-Mar-2013 01:18:48] PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/timezonedb.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/timezonedb.so: cannot open shared object file: No such file or directory in Unknown on line 0
[01-Mar-2013 01:18:48] PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/suhosin.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/suhosin.so: cannot open shared object file: No such file or directory in Unknown on line 0

The previous installation is still active but 'error_log' is not present in it, did I miss something?

Thanks in advance.

Send these errors to your host. They might have to deal with php settings.

Thanks for your reply, I notified the webhost and they already installed missing php modules.

If I like to re-check that there are no more warnings, by any chance do you know how to clear the 'error_log' files? it seems like it has accumulated thousands of records.

Just delete them. They'll be recreated if they're needed. :)
