I sent the following to netbsd-help a couple of days ago, but did not get
a response.  I'm also experiencing the same problem when trying to compile
X from netbsd-current, on the same alpha running NetBSD 2.0.2 for sparc64.

 There's not a single file with "dmxproto" as part of its name anywhere in
my source for NetBSD 2, 3, or current.  Unless anyone has any better
ideas, i guess my next step is to start digging throught the Xfree86
sources.

 I'm building on a DS10 (alpha) running NetBSD 2.0.2. XFree86 is installed
in /usr/X11R6.

  I can't find dmxproto.h anywhere in the NetBSD-3 source tree.

 One odd thing -- when i was downloading the NetBSD 3 source tarballs,
there was not one for x11.  So i just pulled the files from
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-release-3-0/src/x11/ .


I found one mention of this exact error in the
 mailing liosts when compiling X on an alpha:

   Linkname: tech-x11: Building X on NetBSD-3_BETA/alpha fails dmxproto.h
        URL: http://mail-index.netbsd.org/tech-x11/2005/08/25/0000.html


  However, there was no reply. Anyone have any ideas?
