That looks ok...

Not sure what you mean by "spec'd for that". MacPorts builds a port universal if you request it. Also, if you request a port to build universal, and any of its dependencies are not built universal, MacPorts rebuilds those dependencies universal. Also, if you request a port to build, and it needs a different architecture than the architecture for which any of its dependencies are installed, MacPorts rebuilds those dependencies universal, on the assumption that the needed architecture is in the list of universal architectures. This latter case generally occurs on Snow Leopard and up, where the default is x86_64, but some ports only build i386; this isn't expected to happen on Leopard or earlier with the default arch selections.

Certainly "sudo port clean wxWidgets" and "sudo port install wxWidgets" would be a good thing to try.

I am trying to build py27-wxpython on my Tiger PPC Mac and although it's not finished yet it has at least started building wxWidgets, which is more than happened in your case.

Could you show the output of "port -v installed"?
