gpg-agent

[Pollywog]

I have been having trouble getting gpg-agent to work. kgpg complained about 
the agent not running.  I added this to my ~/.bashrc:

GPG_TTY=`tty`
export GPG_TTY

This seems to have taken care of the problem but it only works when my default 
shell is bash.  If my shell is tcsh, it doesn't work.  This is what I have in 
my ~/.cshrc:

setenv GPG_TTY tty

Apparently this is wrong.  Any ideas as to what I can try?
