Exporting Mirrored CVS (with local changes) to SVN

First I have tried the dual independent repos but it says "diffent sources".

Anyway, I have been using svk (1.0) to mirror a remote cvs repos and 
committing my changes to a local repos:

//mirror/cvs-project
//local/cvs-project

This has been working great, but now people want to help with 
development.  The problem is that the main cvs-project is pretty locked 
down (cvs access by ip -- cvs tarball is openly distributed).  So I 
would like to "export" a SVN repo of my //local/cvs-project and let 
people commit to me (and not the main project).

I created a svn repo on my server (svn://myserver/cvs-project) and 
mirror/sync'd it to //export/cvs-project.  When I try to do this:

$ svk cp //local/cvs-project //export/cvs-project

I get "Different sources."

Anyway I'm open to any changes to my svk setup (including starting from 
scratch) if anyone can help me get this crazy setup working.

So to recap -- I want to mirror (just want to track updates) a cvs repos 
to a standard svn public repo where people can commit changes without 
pushing the updates to the true cvs repo.

Thanks in advance,
Jeb
