You are trying to do it the hard way.

First "hard way" shown above. Rather than create a "mynewsyslog",
simply run "/usr/sbin/newsyslog -f /etc/newsyslog.wtmp" from the
crontab. However there is an even simpler way.

Newsyslog runs and decides *if* the files in its config need to be
rotated. You want the file to be rotated no matter what, so why don't
you simply rotate it in the crontab?
0 0 * * 6 root umask 2; DATE=`date +\%Y\%m\%d`; mv /var/log/wtmp \
/var/log/wtmp.$DATE; touch /var/log/wtmp; chown root.bin /var/log/wtmp;\
gzip /var/log/wtmp.$DATE
You might not have to umask or chown as shown above, it doesn't hurt.
The above idea was borrowed from SGI's root crontab. Lately I've been
considering porting newsyslog to SGI, or using the perl lumberjack.
Hmmm. Checking recent sources I see rotation of wtmp is no longer
handled by newsyslog but happens in /etc/monthly. Guessing this is so
monthly accounting works right.
nospam: {261} pwd
/usr/src/etc
nospam: {262} ls -l monthly newsyslog.conf
-rw-r--r-- 1 root wheel 527 Feb 9 05:44 monthly
-rw-r--r-- 1 root wheel 570 Apr 16 20:02 newsyslog.conf
nospam: {263}
