Freeradius, building from sources using unixodbc-dev not libiodbc2-dev package.

I plan to install Asterisk and Freeradius at teh same Ubuntu server, that is to build from sources. But there is dependency conflict. Asterisk needs unixodbc-dev for correctly working with DBs, as Freeradius requires libiodbc2-dev. And it conflicts each other. Is it possible to make Freeradius with unixodbc-dev without functionality lacking ? Or it is not and is libiodbc2-dev only required ?
