well, lookie here:

pts/9 dogcow@mercury: /usr/pkgsrc/x11/xkbcomp 2568 % pkg-config --exists --print-errors "x11 xkbfile"
gnome-config: not found
Package x11 was not found in the pkg-config search path.
Perhaps you should add the directory containing `x11.pc'
to the PKG_CONFIG_PATH environment variable
No package 'x11' found
gnome-config: not found
Package xkbfile was not found in the pkg-config search path.
Perhaps you should add the directory containing `xkbfile.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xkbfile' found

and in the xkbcomp config.log:
configure:3673: $PKG_CONFIG --exists --print-errors "x11 xkbfile"
gnome-config: not found
Package x11 was not found in the pkg-config search path.
Perhaps you should add the directory containing `x11.pc'
to the PKG_CONFIG_PATH environment variable
No package 'x11' found
gnome-config: not found
Package xkbfile was not found in the pkg-config search path.
Perhaps you should add the directory containing `xkbfile.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xkbfile' found
configure:3676: $? = 1
configure:3691: $PKG_CONFIG --exists --print-errors "x11 xkbfile"

should xkbcomp be a prerequisite for the other modular xorg stuff,
if it demands x11 and xkbfile exist?
