Since the shadow maintainers at least gave it a distinct exit code, I
added a really cheap and nasty hack in Ubuntu to work around this; since
the whole situation broke debootstrap, it was blocking a lot of my work,
and I had to do something urgently ...

  &systemcall('/bin/sh', '-c', '/usr/bin/chage -M 99999 ' . quotemeta($new_name) . '; RET=$?; [ $RET -eq 3 ] && exit 0; exit $RET');

I don't know if this is the approach you want to take; a flag to chage
to suppress the error message would certainly be neater, but as has been
mentioned it would require a versioned dependency.
