Last night, I had two systems fail on new amanda libs that I built.  Upon 
investigation, I found
this in the runtar debug logs in /tmp/amanda:

# more /tmp/amanda/runtar.20050217191004.debug

runtar: debug 1 pid 11435 ruid 7510 euid 7510: start at Thu Feb 17 19:10:04 2005
/usr/local/dist/bin/tar: version 2.4.4p4
runtar: error [must be setuid root]

runtar: pid 11435 finish time Thu Feb 17 19:10:04 2005


Yet, an ls -l shows

# ls -l /usr/local/dist/bin/tar
-rwxr-xr-x  1 root root 322664 Feb 16 10:38 /usr/local/dist/bin/tar

And

# /usr/local/dist/bin/tar --version
tar (GNU tar) 1.13.25

I'm can't figure out why runtar is complaining like this.  Any ideas?
