Thanks!  I tried what you suggested, but am still getting the same error message.

  Could not find agda-mode-

Listing from the call to cabal appears below, for completeness, along with my current $PATH.

Any help gratefully received! Go well, -- P

Perhaps the binaries for Agda did not end up on your PATH.

This command looks for "agda-mode-<version>". If you want to use this
command, then you can for instance install Agda using something like
"cabal install Agda- --program-suffix=-" (assuming that
the binaries end up on your PATH). Note that the Emacs mode by default
uses "agda-mode", without a suffix, even if you used the "Switch to
another version of Agda" command the last time you used Emacs.
