htpasswd command: not existant?

My Linux server is SUSE 10.1 64-bit, and I'm running Apache2, php5, MySQL, the latest and greatest.
I'm installing Nagios and it is having me add a user under Apache, however the htpasswd command does not exist.

Code:

---

chpas-cacti:~ # htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
-bash: htpasswd: command not found

---

What can I do to make this work? Is there another way of doing this? Thanks!

I guess I should pay attention more! The instructions for Nagios address "htpasswd," however, I had htpasswd2 and it worked just fine. Now I get to mess with plugins to get the eyes and ears of our network back.
