Note this is the first error, and that's unrelated to enable_if.

This message says a declaration of enable_if is missing.
Either it's not properly qualified, or equal_to.hpp is not including it 
and was relying on other files to include it, which of course is very 
fragile. (missing includes is a very common bug in many Boost libraries 
though)
