Sorry for bothering you again, but I really can't build a -current
iso image using ./build.sh -m i386 iso-image on a Darwin system

iso-image ===> etc
rm -f /usr/src/etc/obj/cdrom.pathlist
echo "i386=/usr/src/obj/releasedir/i386" >> /usr/src/etc/obj/ 
cdrom.pathlist
mkdir -p /usr/src/etc/obj/cdrom.dir
mkdir -p /usr/src/obj/releasedir/i386/installation/cdrom
mkisofs 2.01.01a17 (--)
mkisofs -J -l -hide-joliet-trans-tbl -r -T  -V NETBSD_4993  - 
publisher "The NetBSD Project"  -m "/usr/src/obj/releasedir/i386/ 
installation/cdrom" -quiet -b i386/installation/floppy/boot-big.fs -c  
boot.catalog -graft-points -path-list /usr/src/etc/obj/ 
cdrom.pathlist  -o /usr/src/obj/releasedir/i386/installation/cdrom/ 
netbsd-i386.iso /usr/src/etc/obj/cdrom.dir
mkisofs: Uh oh, I cant find the boot image 'i386/installation/floppy/ 
boot-big.fs' !

*** Failed target:  iso-image-mi

Obviously the distribution target had successfully completed.
What's the reason for this? (I have already asked something about
boot floppies, but it was about building them without ./build.sh)
Thank you very much!
