Help building linuxwacom

[Ali Mazandar]

According to the linuxwacom website
(http://linuxwacom.sourceforge.net/), FreeBSD is a supported OS.  So I
downloaded the production release 0.7.6-4 and setup the configure
script to the best of my abilities.

----------------------------------------
  BUILD ENVIRONMENT:
       architecture - i386
       linux kernel - no
  module versioning - no
      kernel source - no
           Xorg SDK - no /usr
          XSERVER64 - no
           dlloader - yes
               XLib - yes /usr/X11R6/lib
                TCL - yes /usr/local/include/tcl8.4
                 TK - yes /usr/local/include/tk8.4
            ncurses - yes

  BUILD OPTIONS:
            wacom.o - no
            wacdump - yes (no USB)

       wacom_drv.so - no /usr/X11R6/lib/modules/input (no USB)
        wacom_drv.o - no
----------------------------------------

When I ran make, I got the following error messages:

The instructions make mention of a "xorg sdk", however I'm not sure if
these are installed and/or where I can obtain them.  There seem to be
xorg sdk rpms out there for a variety of linux distros but nothing
FreeBSD specific.  Is this something I can obtain from ports?

Any help would be appreciated.

Thank you,
Ali
