The libnvidia-egl-wayland.so shipped in the package does not export the wl_eglstream_interface symbol. It's unclear to me how this has happened; a local build of the library correctly exports that object. This symbol is required for Wayland compositors which want to provide EGL support on the NVIDIA drivers.
Aha! This is fixed in the commit *after* the 1.1.0 release, which is why my local builds see the symbol.
