Well, it was a bug, but not particularly in showconfig alone, see below.

The bad news is that it was a bug in the ports system. It turned out that
because of the way the unique name of the port was set (which happens twice),
the options file is not read from the same directory that it is written to!
Thanks to Baptiste Daroussin for clueing me in in this. I've gained a new
respect for the people maintaining the ports infrastructure. :-) It's kind of
amazing it works as well as it does.
The good news is that there are several workarounds. For future reference, the
workaround that I ended up using was to set the following variable in the port
makefile:
OPTIONSFILE= ${PORT_DBDIR}/py27-${PORTNAME}/options
