I have two perhaps related other problems. First, tcsh was not installed by the install system. I had to compile it from source. Second, the root user does not source its .tcshrc file when I su or log in as root. I have to do this manually.
So you built and its buggy ?
Perhaps the first thing to try would be to install the FC tcsh package ?
(yum install tcsh; hash -r; tcsh)
and see if that works ?
