Paulv is indeed correct here. Using spawn will start a *new* process
(with a unique pid) and therefore it does not interact or have any
knowledge of the shell or environment variables you had when you started
IDL. You might be able to pass the IDL '!PATH' variable in a string when
you use spawn, but you'll need to be careful this concatenated string of
path + command doesn't get too long. Modifying your .login/.cshrc to
append the required path is the cleanest option by far.
