Actually now that I think of it, building your own right now might cause problems because in the repository we have updated to a newer version of AjaxControlToolkit and current releases of Form Wizard Pro and Event Calendar Pro are not compiled against the new version. It would not be a problem except for those products. I will need to make a new release of those products along with the next release of mojoPortal because those libraries changed and they depend on specific versions. I've already updated my local copies.
I will try to get an updated release out soon of both mojoPortal and updated products.
