Yes but it did indeed state "No such file or directory...". Would it be 
that hard for DynaLoader.pm to mention exactly which file it was looking 
for?

I was the one who stated that you need a running X server precise 
because I'd been through this exercise before. It's not really that 
difficult to understand. There is no Tk on native Win32. There may be 
one that was installed when you installed ActiveState. There is none 
when you install Cygwin. You can install Cygwin's Perl/Tk but then 
you'll get one that is designed to work with an X server - just like it 
would have been designed to work with an X server before it was ported 
say on a Linux box. It's not much different than say xterm, which is 
also designed to work with an X server. Rxvt, OTOH, can work with an X 
server or just regular win32 graphical elements but that's the exception 
to the rule.

I'll say it again, it would be wonderful if Perl/Tk would work with 
regular win32 graphical elements but nobody has bothered to develop that.
