as vigr and vipw are in /usr/sbin, its likely that which vigr is failing
if you are joe user, as they will not be in your path.

as root:
sf linux # qpkg -f `which vigr`
sys-apps/shadow *

as nick:
nick@sf nick $ qpkg -f `which vigr`
which: no vigr in
(/bin:/usr/bin:/usr/local/bin:/opt/bin:/usr/i686-pc-linux-gnu/gcc-bin/3.3:/opt/Acrobat5:/usr/X11R6/bin:/opt/blackdown-jdk-1.4.1/bin:/opt/blackdown-jdk-1.4.1/jre/bin:/usr/qt/3/bin:/usr/kde/3.3/bin:/usr/games/bin:/opt/vmware/bin)

An infinite number of monkeys pounding away on keyboards will
eventually produce a report showing that Windows is more secure,
and has a lower TCO, than linux.
