For future reference, here's how I did it...
Step 1) run cdda2wav with the "-tall and "-v" options and do a screen
capture on the TOC output at the beginning. "-tall" dumps all
tracks into one large file "audio.wav". "-v" generates a verbose TOC
Step 2) emerge wavsplit (keywording required on my system).
Step 3) Here's the cddawav TOC diagnostics at the beginning, from the
screencap

On playing audio.wav with mplayer, I determined that the TOC time for
the first track was 3 seconds too long, which threw off everything else
that followed. I tweaked the output in vim, and converted it to...
wavsplit audio.wav -t -H 0:2:10.07 0:2:28.28 0:2:15.15 0:1:53.73 0:2:09.27
0:2:31.00 0:2:17.00 0:2:03.55 0:2:13.50 0:1:52.62 0:2:29.73 0:2:25.28 0:2:18.25
0:2:14.73 0:1:51.20 0:2:06.20 0:2:06.38 0:2:29.37 0:2:03.40 0:2:05.05
wavsplit, as the name implies, splits .wav files. The "-t" option
tells it to do consecutive tracks. The "-H" option tells it to use
hours:minutes:seconds time format. Note that this option requires all
3 fields. A dummy zero is needed for hours in this case. I changed the
first duration from 2:13.07 to 2:10.07, which got things aligned
properly. The result of the command was a subdirectory "audio", with 21
files, "01.wav", "02.wav",...,"21.wav". The last file is 5 seconds of
silent filler, and can be deleted. The remaining 20 files correpond to
the 20 audio tracks on the CD.
