[BusyBox] depmod.pl

[ms419 at freezone.co.uk]

I'm trying to build modules.dep for a powerpc kernel on my i386 host.

I tried depmod, but it segfauls: 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=268720

I also tried the depmod.pl script which accompanies BusyBox, but it 
also seems to be broken:

../../busybox/busybox-1.00-rc3/examples/depmod.pl -b lib/modules -F

Before trying to diagnose depmod.pl, I thought I'd enquire if a more 
recent version is available, or if someone else has already got it 
working?

Thanks,
