You can use "eggdeps" (search pypi for it) to get a tree of all dependencies in your buildout - perhaps this can be helpful. Add the egg to your buildout and rerun buildout. Do it on your original, working buildout configuration, before making the changes you mentioned. (Generating the eggdeps script requires buildout to finish successfully).

add this to your buildout configuration:

parts +=
    eggdeps

...

[eggdeps]
recipe = zc.recipe.egg
eggs = tl.eggdeps
       ${instance:eggs}
scripts = eggdeps

Run buildout again. Now you have a script bin/eggdeps, that prints a tree of all dependencies. Run it:

./bin/eggdeps -n
