 One of the dbus-headers, the dbus-c++-headers and/or the application
 'dbusxx-xml2cpp' where not found. The dbus-server for ffado will therefore
 not
 be built.

 Writing a small C source reveals the problem to be the `-m64` option to
 gcc:
 {{{
 #include <inttypes.h>
 int main(int argc, char* argv[])
 {
         return 0;
 }

 $ g++ -c foo.c -Wall -m64
 In file included from /usr/include/inttypes.h:26:0,
                  from foo.c:4:
 /usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file
 or directory
 compilation terminated.
 }}}

 I changed the SConstruct:
 {{{
 --- SConstruct  (revision 2426)
 +++ SConstruct  (working copy)
 @@ -577,7 +577,7 @@
      # build for 64-bit userland?
      if env['DIST_TARGET'] == "powerpc64":
          print "Doing a 64-bit PowerPC build"
 -        env.MergeFlags( "-m64" )
 +        env.MergeFlags( "-mpowerpc64" )
      elif env['DIST_TARGET'] == "x86_64":
          print "Doing a 64-bit x86 build"
          env.MergeFlags( "-m64" )
 }}}

 and it now compiles.
