FFA for Asterisk

I have installed FFA following the info in the readme file. I have registered the product using the register utility.

The first problem is that the fax module will not load it puts out the following message

/usr/lib/asterisk/modules/res_fax_digium.so: undefined symbol: ast_fax_state_to_str

The second issue is that it does not show up in the registered products. I used the fax_bench app to download the prescott_32 version of the res_fax_digium.so

Can anyone help ???
