My manual steps for installing the bootloaders are

  cp /usr/mdec/ofwboot /boot
  installboot /dev/rsd0c /usr/mdec/bootxx /boot

'installboot' has to know the real secondary bootloader ('/boot').

Does this work for you?

Hmm, I never had a macos partition left after netbsd installation
(;-)), so simply

  boot scsi-int/sd@0

did the job for me.

I guess putting ofwboot.xcf on a macos (hfs) partition (# 4 in your
case) would be an alternativ resulting in a boot command like

  boot scsi-int/sd@0:4,\ofwboot.xcf scsi-int/sd@0:5,/netbsd

Maybe this helps,
