That works, but something in MacPorts breaks. I can do `port patch freetype +infinality` to check whether the patches apply correctly, but when I continue with `port configure freetype +infinality` the process continues all the way to the install or until the 1st error.

I don't think we ever intended the version to be changed inside a variant. I would consider it a maintainer error to do so. I don't think the portindex accommodates more than one version per port, and the portindex is used to determine what ports are outdated.
