error when I install mysql-odbc

 dear:

I encountered an error when I installed "mysql-connector-odbc-5.1.8". I don't know what is wrong.

cpu: x86_64
mysql-5.5.15: Installed
unixODBC-2.3.0: Installed

shell>./configure --prefix=/usr/local --with-unixODBC==/usr/local --with-mysql-path=/usr/local/mysql

Success!!

shell>make
