There must be something else going on, since it works for me.
No doubt you know that `set path = ..` does not set the environment
directly, but sets a csh variable that sets the environment variable PATH.

/usr/bsd/which is just a csh script.  It even has comments.
`csh -x /usr/bsd/which foobaz` might illuminate what is going on.
