Asterisk at home & mysql5

hello people!
ive been happy since the day aah came up to my life
now i came to find trouble, given the fact that trying to modify anything cause problems
ive tried to update mysql to version 5 (which i have) and to make it work with asterisk (which i havent).
when asterisk is coming up i get this on the log files:

Oct 3 10:50:45 VERBOSE[2793] logger.c: []Oct 3 10:50:45 WARNING[2793] loader.c: cannot open shared object file: No such file or directory
Oct 3 10:50:45 WARNING[2793] loader.c: Loading module failed

has anyone succescully made mysql5 run with asterisk on AAH (CentOS)?
thanks in advance
