Yeah, that doesn't include a value for $! which is very weird .... which is why you should use Fudge() to get more info

Also what version of perl do you have, and what filenames are involved?

Do a Data::Dump::dd( $source, $target ) and post that

Then try File::Copy::copy( ... ) or die Fudge(); where ... is copy/paste of ::dd output

Then try getting/installing the latest http://perl5.git.perl.org/perl.git/history/HEAD:/lib/File/Copy.pm and try again

File::Copy::copy shouldnt die without setting $!
