+@item The Curses based Pinentry does not work

+The far most common reason for this is that the environment variable
+@code{GPG_TTY} has not been set correctly.  Make sure that it has been
+set to a real tty devce and not just to @samp{/dev/tty};
+i.e. @samp{GPG_TTY=tty} is plainly wrong; what you want is
+@samp{GPG_TTY=`tty`} --- note the back ticks.  Also make sure that
+this environment variable gets exported, that is you should follow up
+the setting with an @samp{export GPG_TTY} (assuming a Bourne style
+shell). Even for GUI based Pinentries; you should have set
+@code{GPG_TTY}. See the section on installing the @program{gpg-agent}
+on how to do it.
