pload won't build

["Steven M. Bellovin" <smb%cs.columbia.edu@localhost>]

When I try to build net/pload, I get

===> Configuring for pload-0.9.4nb3
imake -DUseInstalled -I/usr/pkg/lib/X11/config -I/usr/pkg/xorg/lib/X11/config
Imakefile.c:16: error: Imake.tmpl: No such file or directory
imake: Exit code 1.
  Stop.
mv -f Makefile Makefile.bak
imake -DUseInstalled -I/usr/pkg/xorg/lib/X11/config
Imakefile.c:16: error: Imake.tmpl: No such file or directory
imake: Exit code 1.
  Stop.
===> Building for pload-0.9.4nb3
make: don't know how to make all. Stop


This is with pkgsrc HEAD, on -current and 3.0.1.
