xserver distribution problems

[vehemens]

Found some breakage a while ago creating a xserver distribution on my FreeBSD 
box.
1) in dix, fails looking for dix.c.  DTRACE option?
2) in os, fails looking for os.c.  DTRACE option?
3) in hw/xfree86/os-support, fails with: Could not find ./.deps/solaris-.Plo. 
os related?
4) in hw/darwin/quartz, fails with: don't know how to make quartz/Xserver.m. 
os related?
5) GL/glx: glxbyteorder.h missing from distribution
6) include: xkbsrv.h missing from distribution
