[NEWBIE] Error - Search for program: no such file or directory, ls

[Robert Pollard]

Hello all,

I have the error indicated in the Subject when I execute C-x C-f and 
try get a directory listing.  The same occurs when I enter dired and 
try to get a directory listing.  I have an idea of what needs to be 
done but I don't know what to do it with.  The last time I saw 
something like this I had to set a variable to tell it where the 
executable was.  I assume a variable of some type is not set up 
correctly.
Whatever it is I would appreciate a pointer in the right direction.

OS:	     Mac OS X 10.2.6
EMacs: 21.3.50.1

Thanks,

Robert Pollard

See the insert-directory-program variable and the lisp/ls-lisp.el file.

Hey Kevin,

Thanks for your time.  I just have a couple of questions  if you don't 
mind:

My path is set to the where the ls program is located.  I found this by 
using "which ls" and it located it in /bin.  This path is defined in my 
PATH variable.  So what is broken that prevent EMacs from finding the 
program?
If ls-lisp.el is not loaded does it use file.el instead to find the 
programs?

Thanks for your valuable time,

Robert Pollard
