Hmmm,  Ok, how about changing this part:

> >>    @args = ("tar", "cf", "archive.tar", <*.html>);
> >>    system(@args) == 0 or die "system @args failed: $?";

To read something like:

> @args = ("tar", "cf", "archive.tar");
> @args2 = (<*.html>);
> system(@args, @args2) == 0 or die "system @args failed: $?";

And see if you get the same error.  Question is to find out "what" about the 
line that the server does not "like"....  EG what is causing the error.
