Build options built by dialog(1)

[Chuck Bacon]

I stumbled into a problem trying to get xorg up on my
current 9.0-RC1.  I selected an intolerable choice,
notable PTH.  Now the choice of Python causes the build
to fail, and I can't find the output of dialog(1).
Question:  How can I restart the build with a new
dialog(1)?  Put another way, where are the various
build variables kept?
Once again, this old 650-704-7070-PDP4-KA/KI/KL/KS-CTSS-
Convex-IBMPC-3B1 warrior needs help :-}
