If you're using it via CGI you'll probably want to
use CGI and print HTTP headers using CGI. I think that's your problem.
use CGI;
print CGI->new->header;
At the top should suffice.
perldiag points to several sources, stating that this is a CGI error.
As this is an alien error,
use diagnostics could have not explained forther.
see perldoc perldiag, and search it for "Server error" for more details.
P.S. You should really use File::Copy, as it's a simpler interface, and platform independant (at least externally, i dunno about it's guts). The code I gave was just to show you how it can be done manually.
