The OS X Tk (the Perl module) is probably compiling against the *NIX-y Tk (the Tcl extension) which is going to try and talk to an X server. There may be an OS X "native" (in that it's talking via Carbon or Cocoa rather than going through an X server) Tk version, but I'm not aware of such a beast. Given that X11.app is not installed by default but it does ship on the OS installation media, you need to consider if having one easily fulfilled dependency is worth the unknown hassle of getting the (possibly non-existent) native Tk going.
