login fails to source ~/.tcshrc under xterm

Hi All,
First off, I'll apologize for crossposting. I never do that, but
I am unsure which group will answer this question best.
I have some servers with Red Hat Enterprise Linux 2.1. Agetty
starting login with the terminal type "xterm" and the user has
starting shell /usr/tcsh...
The problem I currently have is this: the login process is reading
/etc/csh.login and /etc/csh.cshrc BUT IS NOT reading ~/.tcshrc OR
~/.cshrc. How can I beat this machine into submission?

Your buddy,
Andy
