My build of pkgsrc editors/emacs does not have x11 included. why ?
Simple open up emacs-23.2 ( at /export/local-src) and ./configure (without any argument), gives:

  Does Emacs use toolkit scroll bars?                     yes

This problem turned out that my /etc/mk.conf was wrong. The (trace of) setup for Mac OS X were there,

PKG_OPTIONS.emacs_current = -dbus -gtk -svg -x11 -xft2 -xaw -motif 
#KG_OPTIONS.emacs_current+= nextstep

And I misunderstood that -x11 meaned enable x11 as like shell options. By removing this setup, emacs on unbuntu get x11 capability (2010/06/09 added).
