[Zope-CMF] CMF Installation does not show up

[sharif islam]

I just installed Zope from source (Redhat Enterprise AS 3). Then I
followed the directions on the website.
1. Downloaded CMF-1.5.1.tar.gz
2. untarred and extracted it
3. Copied the CMF folder to /opt/Zope/lib/python/Products.
4. Restarted
Then when I go the manage website, in the Products section I don't see
any option for CMF. What is wrong? Thanks.
