Crosscompiling from Solaris 10 - nbpax: unknown group `wheel'

[Hubert Feyrer <hubert%feyrer.de@localhost>]

building netbsd-5 on solaris 10/x86 gives:

...
--- all-bootfloppy ---
--- boot1.fs ---
#    create  bootfloppy/boot1.fs (from: boot boot.cfg  netbsd)
PAX=/usr/homes/feyrer/cvs/src-5/obj.i386/tooldir/bin/nbpax 
/usr/xpg4/bin/sh 
/usr/homes/feyrer/cvs/src-5/distrib/common/buildfloppies.sh  -i 
"/usr/homes/feyrer/cvs/src-5/obj.i386/tooldir/bin/nbinstallboot  -mi386 
@IMAGE@ 
/usr/homes/feyrer/cvs/src-5/obj.i386/destdir/usr/mdec/bootxx_ustarfs" -p 
-m 3 -s .fs  boot 2880 boot boot.cfg  netbsd
nbpax: unknown group `wheel'
nbpax: failed at line 1 of the specification
*** [boot1.fs] Error code 1
1 error


Anyone know how to fix this?
