misc/zoneinfo port on 6.1R and others

[Kevin Kramer]

I've portsnapped my servers (some are 6.1R, 6.2 Prerelease, 6.2 Beta2 
etc) to get the lasted zoneinfo port. Prior to this I tested the 
timezone info using
zdump -v /etc/localtime | grep 2007 , the test showed I had old DST 
information. I installed the port without issue and re-ran the tzsetup 
according to my timezone (CST).

then I re-ran my test and it never returns, however another test (found 
in other threads) works

date -r 1173679260, on all the hosts.

Does this mean I'm really OK or do I need to have the zdump work? I have 
not rebooted the hosts as suggested in other threads, I really can't. 
Some of them I've updated the source, cd  /usr/src/share/zoneinfo && 
make && make install then tzsetup and still get a hang.
