This works for me without a bad message:
#!/usr/bin/perl
# vi:ts=4 sw=4 et:
use strict;
use warnings;
my $fname = $ARGV[0];
my $scan_foo = 1;
eval "use File::stat";
if ( $@ ) {
$scan_foo = 0;
}
if ( $scan_foo ) {
my $foobarzlot = sprintf("%d", File::stat::stat($fname)->size );
print "FOOBARZLOT=" . $foobarzlot . $/;
}
__END__
