Now, since you didn't provide a py24-* subport, the behaviour defined in the python portgroup for running install without specifying a version (as opposed to specifying it, like `port install py26-pdfrw`) is to specify a dependency on the 27 version of the port (py27-pdfrw).

Yes—provided you've already added the line "python.versions 27" (and possibly any other python versions you want to support, e.g. "python.versions 25 26 27").

There are other nuances of unified ports. The best documentation is to read existing ports using the portgroup—there are tons of them.
