I should be more clear. I'd try including \usepackage{amssymb} in macros.tex and see if you can build to HTML without errors. If errors occur, then try limiting the include to non-HTML output. It is curious that other symbols are rendering perfectly given this lack of inclusion for amssymb... but this may have to do with the loading of OT2?
