The latest powerdns seems to work fine on OpenBSD, with the MySQL backend, after compiling powerdns with GCC 3.2 or 3.3 from the OpenBSD ports tree. (CC = egcc, CXX = eg++). It appears to link fine when linked with OpenBSD's libpthread and MySQL's libmysqlclient both compiled from the stock system compiler. -- One nation, under surveillance.
