How did you transfer them? FTP? Many FTP clients will choose to transfer some files (often using the file name as a hint as to whether it's appropriate) in "ASCII mode" which means that it will change the line to the standard line endings for the local system during transfer.

Try replacing your /\n{2,}/ regular expression with:

/(?:\r?\n|\r){2,}/

... which should match two or more occurrences of any common line ending.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
