[MySQL]ERROR 1126 (HY000) Permission Denied problem

Hi,

After looking at many different sites and forums I have not been able to find a solution for this problem, I have pasted this from a forum post I made last week.

Hi,

On the ubuntu 9.10 server edition I have been trying to add the Maatkit plugin for MySQL, prior to 9.10 I haven't had a problem as such, This is the MySQL query that I am trying to run:

CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'fnv_udf.so';

This is the error I keep getting:

ERROR 1126 (HY000): Can't open shared library 'fnv_udf.so' (errno: 22 /usr/lib/mysql/plugin/fnv_udf.so: failed to map segment from shared object: Permission denied)

The folders mysql & plugin, did not exist so i created them also i have changed the permission on the "mysql" & "plugin" folders and also the fnv_udf.so file to mysql:mysql

I am trying to use the udf to create the function fnv64(), i used this on a Ubuntu 8.04 LTS Server on which it worked.

Any help given to this problem I am getting will be greatly appreciated in advance
