Try:
chflags -R noschg * in /var/tmp/

Presumably you ran mergemaster at some point which creates the
/var/tmp/temproot hierarchy and sets some system 'immutable' flags on
some of the files in there to stop them being modified.  Running
'chflags noschg' removes the immutable flag.

For more info, man chflags and man ls

Specifically try ls -loR /var/tmp/

For example on my system:
[12:13:19] munk@users /home/munk# ls -lo /kernel
-r-xr-xr-x  1 root  wheel  schg 3132649 Apr 18 14:42 /kernel

you can see the 'schg' flag is set on kernel to stop it being modified.
