PHP Warning:  PHP Startup: Unable to load dynamic library
'/usr/lib64/php/modules/mysqli.so' - /usr/lib64/php/modules/mysqli.so:
symbol client_errors, version libmysqlclient_16 not defined in file
libmysqlclient.so.16 with link time reference in Unknown on line 0

I guess I need to rebuild php. Apart of this for now works ok on my F14 :)
