>Description:
I crossbuild netbsd-5-1-RELEASE on Linux amd64 (Debian Lenny) for NetBSD i386 
(with clean obj.i386)

===> build.sh command: ./build.sh -m i386 -U -O /srv/netbsd/build/obj.i386 -T 
/srv/netbsd/build/tooldir -R /srv/netbsd/build/releasedir -X 
/srv/netbsd/usr/xsrc -x -u release
===> build.sh started: Tue Nov 23 09:25:20 CET 2010
===> NetBSD version:   5.1
===> MACHINE:          i386
===> MACHINE_ARCH:     i386
===> Build platform:   Linux 2.6.26-2-amd64 x86_64
===> HOST_SH:          /bin/sh
===> TOOLDIR path:     /srv/netbsd/build/tooldir

===> RELEASEDIR path:  /srv/netbsd/build/releasedir
===> makewrapper:      /srv/netbsd/build/tooldir/bin/nbmake-i386
===> Updated /srv/netbsd/build/tooldir/bin/nbmake-i386

The build process failed here:

On this command:

/srv/netbsd/usr/xsrc/external/mit/libXfont/dist/src/fontfile/bunzip2.c:40:19: 
error: bzlib.h: No such file or directory

"bzlib.h" is in "/srv/netbsd/build/obj.i386/destdir.i386/usr/include", but this 
directory is not include in command line.

If bzlib.h is not existent in build platform, build failed. Else, build success.

I am not sure the correct thing should be using "bzlib.h" of build platform (if 
versions mismatch, for example)

Better should be use "bzlib.h" of netbsd source tree (in destdir/usr/include)

(I have a typescript (70M) for the build without bzip2 headers. The typescript 
for the build with headers is in progress)
>How-To-Repeat:
1. Get netbsd-5-1-RELEASE from cvs (src + xsrc)
2. Cross-build with ./build.sh -x release on a Linux platform without bzlib.h
>Fix:
Depending the problem is doc-bug or sw-bug:

- src/tools/compat/README should mention bzip2 headers are need for 
crossbuilding NetBSD 5.1 src+xsrc on Linux (but were not need with 5.0.2).

- src/external/mit/xorg/tools/bdftopcf/Makefile should include 
"-I${DESTDIR}/usr/include" (but should exist a variable for that)
