The C shell keeps an internal hash table for finding commands in your $path.
This table is built when you log in, if you add a new executable to a
directory in the path you need you tell the C shell to rebuild it's hash
table.  The easiest way of doing this is via the 'rehash' command.  At the
% prompt, just type 'rehash', and csh will be able to find the new
executables in the path.  Alternatively, you can log out and back in again,
or "re-setenv" the path variable as you have been doing.
