I've got exactly the same problem recently even twice. 
The first time was gone by starting from scratch. I did NOT
figure out what was wrong.

The second time, I now know the problem. csh flags this line
when evaluating variable $@.
The problem is:
-------
% csh      
% echo $@
Illegal variable name.
-------
While if it is /bin/sh, 
-------
% sh
$ echo $@

$ 
-------
This means (at least to me), I had some trick to my shell.
I had carefully checked my shell environment in chrooted pbulk,
and this issue resolved.

I am writing this mail mainly for my record. I may have the same 
thing in the future ;-(
