ERROR 1126 (HY000): Can't Open Shared Library(install UDF to mysql 5.1 in ubuntu 9.10)

I try to install mychem3.0.6 into mysql5.1 in ubuntun 9.10 enviroment, and all things have been built, just in the last step i encounter an error about can't open shared library when i import sql to mysql(udf). I search the solution by google, that's great i found it and it works well now.

it caused by ubuntu apparmor, so you just need to disable it.

touch /etc/apparmor.d/disable/usr.sbin.mysqld

/etc/init.d/apparmor restart

/etc/init.d/mysql restart

all above commands need root account.
