In your application's buildout.cfg you can add a versions section,
something like so:

  [versions]
  ZODB3 = <wantedversion>

This will override whatever version for ZODB3 is pinned in the *.cfg
file your app's buildout.cfg extends from. You can do this for all
package you want different versions for (assuming these version are
compatible of course).
