FreeTDS and ODBC 64bit

I am trying to setup ODBC and FreeTDS with Asterisk. I am running CentOS 5 64bit.
I installed unixODBC and FreeTDS from yum, and configured the ini files. If I connect from the linux command line with isql I can connect and run queries.

I tried to enable FreeTDS and ODBC for asterisk via configure, but it keeps telling me I do not have the required packages installed. I am assuming it is because configure is looking in /usr/lib for the libraries when they are in /usr/lib64.

How can I get configure to see the libraries and let me configure and install odbc support?

Never mind I got FreeTDS up and working, I had to install the dev files for FreeTDS it was not enough to just have the library installed.
