[Distutils] buildout behavior as source revisions change

[John Griessen]

Some weeks ago I made a buildout config using mr.developer and djangorecipe extensions
that worked to get a svn trunk version of django-mptt
and now it stops with an error message.

Is there a way to specify sources better so it still works when a rev number changes?  Do I have a syntax error?
The place it has trouble with is     rev=>0.2.2

Now I think I can do without the svn version since django-mptt is now at 0.3.0.

$ bin/buildout output from past the error message
------------------------------------------
    Getting distribution for 'django-mptt-2>0.2.1'.
    zip_safe flag not set; analyzing archive contents...
    mptt.tests.settings: module references __file__
    mptt.tests.test_runner: module references __file__
    Got django-mptt-2 0.3.0.
----------------------------------
The Getting line above says the   rev=>0.2.2 didn't get used anyway?
Know why not?  Is this a mr.developer problem?

Please give my buildout config a look and suggest how I can learn this better.
The config and the error output follow.

Thanks,

John
