No, for one '--relocatable' does not update 'virtualenv/bin/activate' script. Yes you can fix that by re-running virtual env setup as zeekay suggested, however that stills fails to import any 'pip -e git ...' installs which are placed in 'virtualenv/src' so you will have to re-run those pip installs manually.
As I have gained experience as a developer I now avoid additional layers of dependency and abstraction which just have a tendency to be points of failure.
So now I don't install with pip editable (-e) and if needed manually clone repositories into 'project/src/' as opposed to 'project/virtualenv/src' and have the below auto_prep_pythonpath.py script loaded prior to launching my project (I reference it in my django.wsgi script).
As a side note I append 'tailored' to any packages placed in 'project/src' that are modified/hacked so this way I don't have to worry about backward compatibility and I track all source under code control as online repositories can and will brake on you.
Hope this helps.
