Figured it out.

For anybody else that walks into this:
1) On "Source" machine, In Thunderbird Menus: Enigmail -> Preferences ->
Transfer Settings -> Export Settings and Keys
2) On "Destination" machine, In Thunderbird Menus: Enigmail ->
Preferences -> Transfer Settings -> Import Settings and Keys

If you get "You do not seem to have the secret key for  xxxx on your
keyring; you cannot use the key for signing.", you need to copy your
~/.gnupg directory from your source machine.

After you copy, YOU MUST RESTART your GPG/Keyring daemon.  On Ubuntu
derivatives, the command  "gnome-keyring-daemon -r -d" should do it.

After you restart, check your access & setup with "gpg --card-status". 
If you get messages about a missing scdaemon, install it. "sudo apt-get
install scdaemon" worked for me.  YMMV

Restart Thunderbird, and you should be good to go.

Steve
