Cannot install MySQL Connector ODBC on AIX6.1

Dear Sir/Madam,

I installed unixODBC (unixODBC-2.3.0.tar.gz) on the machine.
Then I downloaded MySQL Connector ODBC
(mysql-connector-odbc-5.1.7-aix5.3-powerpc-64bit.tar.gz)
And copied all the files located at
mysql-connector-odbc-5.1.7-aix5.3-powerpc-64bit/lib to /usr/lib/
When I run the install file
(mysql-connector-odbc-5.1.7-aix5.3-powerpc-64bit/bin/myodbc-installer), then
the error occurred(show following):

exec(): 0509-036 Cannot load program ./bin/myodbc-installer because of the
following errors:
        0509-150   Dependent module /usr/lib/libodbc.so could not be loaded.
        0509-103   The module has an invalid magic number.

How can I solve it and install the MySQL Connector ODBC successfully?

Best Regards,
Kenneth WON
