I've untangled this yesterday, it seems the problem was that the package
in question relied on a .pth file installed by another package in the
same directory, so it didn't provide its own .pth file. When everything
was symlinked to one directory (buildEnv scenario) this assumption held,
so the package worked.

To my future self: Python not only searches packages in site-packages
directory, but also searches there for .pth files, which list additional
paths to be searched.
