Source Install Initialization

[buttars]

I'm trying to build and install the zcs-3.0.0_M2_740-src.tgz release on FC4. I built the ThirdParty apps from source as well into the appropriate dir under /opt/zimbra and re-packed them and installed them into the ThirdParty/appname directories. I then ran ant in ZimbraServer and then make in ZimbraBuild with no complaints. Things 'look' good under /opt/zimbra after the install is complete. BTW, I'm using the install guide at:
http://www.zimbra.com/blog/archives/2005/08/index.html
Things go well until I run:
/opt/zimbra/libexec/zmmyinit

I get this output:
Error: assertion '-x /opt/zimbra/mysql/scripts/mysql_install_db' failed

The path in the script is wrong for the install I just did.
So I adjust the path in the script, and then get the following output:
[pykyo@pykyo libexec]$ ./zmmyinit
* Creating required directories

/opt/zimbra/bin/zmmycnf: line 47: /opt/zimbra/bin/get_plat_tag.sh: No such file or directory

So, is the guide I'm using outdated/wrong?
Did I just screw up the install somewhere?
Is there comprehensive source install documentation I haven't found yet?

Don't build the M2 source, it's way way way out of date.

Check out the cvs CRAY branch (info somewhere in the forums on the location) and you'll get a much better system.
