I've volunteered to help find a solution to this situation, but with the underwhelming reception that got I'm not that enchanted to insist.

Portindex? I'm pretty sure I've had a ui_msg for a while in one of my PortGroups without ever running into side-effects.
I kind of appreciate certain messages in the portindex output, in fact.

I doubt that, esp. not if you consider the possibility (and overall good idea) to extent `port info` to print information for machine reading.

As I said, I do not want to disallow building the port on a standard 10.6 because that worked just fine when I was still running 10.6 myself. I can confirm now that gcc 4.7+ still builds the code. Evidently I cannot run it on 10.9 because of a C++ runtime conflict that won't exist on 10.6 .
A pre-fetch fail is acceptable only if there's a way to introduce a variant that will let the code build with an appropriate gcc compiler of choice.

Yes, I noticed one reason which Marko had caught before pushing (but without leaving me the time to address it). The Qt5 subport will probably fail because there currently is no Qt5 for 10.6, but that applies to all Qt5 dependents.
That's all I've been able to glean from the ragtag buildbot output that's been flooding my MacPorts in folder.
