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 p=
ort
makefile:
OPTIONSFILE=3D ${PORT_DBDIR}/py27-${PORTNAME}/options
