Dear Harry,

Thanks for replying - it gives me hope :)

Please find the output of the apache error log using Carp as directed
before the offending line in subject.pm:

j've been trying to track down the same problem on Windows; I thought it
was a problem with Windows or the user's setup.

Can you add these two lines above the line with the error:

 	use Carp;
 	Carp::cluck "in Subject.pm";

The Apache log will hopefully pick up a stack trace which might help.
Can
you post it?
