 I have built a small package for this, available at

 This is exactly the root of the problem. According to the file
 "Change.log" from p5-Tk:
 
   Change 3205 on 2004/03/17 by nick@llama
 
         Re-factor DragDrop:: Rect and SunDrop so latter works again
         while keeping the fix to local and XDND protocols.
         Remove KDEDrop and KDESite (a weak ad hoc protocol used by KDE 2).
 
 The files SunSite.pm and XDNDSite.pm are still part of p5-Tk but
 KDESite.pm is not.
 
 The bad behaviour you write about probably refers to the character
 sequence "\x(d)". I see this as well if I open the file t-pad-4.0.4.pl
 but I can avoid it by enabling the option "CR/LF conversion" from the
 "Misc" menu before loading the file. This is simply the way t-pad
 displays text files coming from Windows, ie with carriage return+linefeed
 as line separator.
 
 I could not test actual drag-and-drop behaviour, no KDE here.
 
 Since pkgsrc can do nothing about the vanished KDE support and the
 strange line breaks are not strange at all, I believe this PR could be
 closed.
