One of my coworkers was showing it off on his Linux machine, so I
decided I has to get it compiled under FreeBSD before I went home...

The following _almost_ works.  I must have forgotten a #define
somewhere, as DBMLibrary gets #defined to 0, which screws up line 89 of
Xvnc/programs/Xserver/Imakefile.  The link line ends up with a "-lm 0"
at the end.  I'm not sure what lines 86-90 are trying to do (should I
#define XFree86Version in FreeBSD.cf?).

1. Adjust the Imakefile in the root directory to remove the "unset" stuff

2. Create a minimal FreeBSD.cf file in Xvnc/config/: (This could
   probably be improved; I've never used xmkmf so I don't know what
   #defines are required.  I just kept adding things until I got a
   clean compile)
  
	#define OSName			FreeBSD
	#define OSMajorVersion		2
	#define OSMinorVersion		2
	#define HasPutenv		YES
	#define HasShm			YES
	#define AvoidNullMakeCommand	YES
	#define BuildPexExt		NO
	#define HasNdbm			YES
	#define XvncServer		YES
	#define DBMLibrary		NO

3. add to Xvnc/config/site.def.vncxmkmf, around line 53 

	#ifdef FreeBSDArchitecture
	#define ProjectRoot /usr/X11R6
	#endif 

4. xmkmf ; make world ; ./vncinstall /usr/local/bin
