Did you try Google? http://lmgtfy.com/?q=Bad+%3A+modifier+in+%24+(%2F).

Looking at the first few results, it looks like the problem is probably a syntax error in one of your startup files where it is trying to set an environment variable. This could be in .cshrc, .tcshrc, .login, or a few others (see the tcsh man page) for a list of files read on startup.
