I ran into issue when tried to compile driver with -ssl option.
Test "def CheckLinkSSL(context)" from SConstruct is not passed.
I checked config.log and it tries to build simple ssl test with gcc (because of *.c extension of generated file), but with boost_regext, boost_thread libraries.
It can be fixed simply by fixing dependencies for test or renaming that file to have cpp extention - g++ will be picked up.
