Aha!  The vital clue!

I get "No such file or directory", but the other file in that directory
claims version 0.2.0, not 0.2.3.  I went back to the 0.2.3 sources and
did make install again just to be sure, but I still get the 0.2.0 module.

I decided that the install must be declining to write over an existing
file somewhere, so I did a find in the kernel modules and discovered
I had TWO files named p80211.o and TWO files named prism2_cs.o -- not
a good sign.  I deleted all of them, and did make install again, and
now "iwlist wlan0 scan" works.

That's a pretty weird problem to have, but I'm glad to have found it
and fixed it.  Thank you for your help.
