I've not used that particular howto so I'm not sure how accurate it is, but
being a wiki you can make improvements yourself if you feel motivated.

I believe this only applies to remote access via svnserver, but if you use
apache then you let apache deal with auth issues and the passwd file in the
svn conf dir is unneeded.

I believe these issues are related to a message you first encountered
(below) when setting up the trac projects.

Some of this howto is not too specific due to the myriad ways these various
bits of software can be set up (eg, one project per repo for svn, one shared
root for trac, etc).  Trying to cover all possibilities would make an
enormous document, and trying to make it only cover one method means
everyone would be stuck with that one particular setup; the latter would
have issues for anyone with an already-existing install of some of it who is
trying to add onto it.

Note that having writting that particular howto I can say that it can work
though it is entirely possible that something has been missed as this is the
first bit of feedback I've had concerning it.  Note also that the current
incarnation is written from a 10.5-point-of-view, though one issue between
10.5 and 10.4 is _www vs. www user names which it appears you've figured
out.

This, I believe, is the cause of your problems, when you first initialized
the trac environment, it wasn't able to properly hook up to subversion.  The
first thing is to make sure permissions are correct across the board; since
you'll be using apache (user www) for access to trac, and I'm guessing svn
access if you use apache+DAV, then www needs to have access to
/svn/MVC_Project as well.  Also, you need to be the www user when you setup
the trac environment by running trac-admin.
