Right, you now get the new error in comment:ticket:32840:13. This is not a problem because there is no reason to install the stub port really. I expect Joshua will fix it within a few hours or whenever he's next around.

Ok, so py27-mysql is already installed. Go use it. :)

Sure. The error will remain until someone fixes the python portgroup. I'm leaving it for Joshua to do since he wrote the subport feature in MacPorts and rewrote the python portgroup to use subports, and understands best how it works and how he'd best like to fix it.

It will block you from installing or updating any python portgroup stub ports that don't turn of linking of binaries (which is most of them). But again the stub ports don't do anything so this isn't a problem. Install or update the applicable subports (those with python version numbers in their name) instead; you should be doing that anyway, since only you know which version of python you want to use the modules with.
