pkg_add on 64bits kernel w/ options MAC

[Jerry Toung]

Hi List,
I am running into a weird issue. On a 6.2 stable, 32bits built with options
MAC,
I can run pkg_add of anything. But a 6.2 stable, 64bits built with MAC won't
let
me do pkg_add. If anybody has an input, please advise. Below is the output
on the 64 bits machine:

net3# pkg_add test.tbz
+CONTENTS: Can't update time for +CONTENTS: Operation not permitted
pkg_add: tar extract of /wr/home/webmgr/test.tbz failed!
pkg_add: unable to extract table of contents file from
'/wr/home/webmgr/test.tbz' - not a package?
