There appears to be an occasional proble with LXConsole installer when trying to install an updated version.
If you are getting a message like "nothing to install" or "can't install because a newer version exists", Try this:
In the Library folder of your hard drive look for the Receipts folder. In there may be a package receipt for LXConsole.pkg. Delete this file and try to install.
If this doesn't allow you to install, go to the Terminal and type:
sudo pkgutil --forget com.claudeheintzdesign.lxconsole.pkg
(yes, there are two dashes before forget)
