You have carriage return whitespace at the end of your input, most likely because your input file is formatted with "Windows" newlines, that is \r\n.

Data::Dumper will show you that whitespace when you set $Data::Dumper::Useqq = 1.

Personally, I like to, instead of chomp, use s!\s+$!!, to remove all kinds of whitespace at the end of input lines.
