enable_if definitely needs SFINAE and cannot be used on compilers that
fail to support it. What libraries do you need? You did not provide the
complete error message so I don't know where this error comes from, but
might want to specify only the desired ones using --with-xxx command line
option to bjam (use bjam --show-libraries for a list).

Where such a claim is made? In general, no such claims can be made about
*all* of boost.
