Prior to that, users could choose "images" mode or "archives" mode, with "images" mode as the default. images_to_archives.tcl converts an "images"-based MacPorts installation to an "archives"-based one.

images_to_archives.tcl runs as part of every selfupdate, ever since MacPorts 2.0.0, in case you're upgrading from an earlier version. If the conversion has already been done, the script should do nothing. I don't know why you received an error.

That's correct, yes. Overriding configure.optflags at the command line should work, provided the port respects that variable and that changing it does not break the port, though it is not intended to be set by users on the command line; it is intended to be set by port authors in the portfile.
