I didn't even think about the documentation. If you use the 'math' directive you have to have latex. If you are going to use any latex math constructs in the documentation you need latex. Considering what sympy is you will need math constructs at some point to document it so latex is required to make html. Considering that latex is free I don't think that is a big deal. Also consider that whoever will be using sympy probably also does latex. Meanwhile I will modify latex_ex so that it produces a latex file and does not generate an error even if latex and xdvi are not present.
