app_rxfax & app_txfax undefined symbol fax_release

Hi, I am trying to setup faxing with * and have installed spandsp as well as the app_rxfax & app_txfax modules. When I try to compile * I am getting the warning:

undefined symbol ‘fax_release’

in both modules. I am using asterisk CVS HEAD release anybody know what to do to fix this?

Thanks,
Josh
