Install option --skip-gst-python fails

[codethief]

I just tried to install gstreamer-python while skipping gst-python and installation failed.

Error logs:

gstreamer-python-install-error.txt

Steps to reproduce:

git clone git+https://github.com/jackersson/gstreamer-python.git
cd gstreamer-python
pip3 --user install . -v --install-option "build_py" --install-option "--skip-gst-python"

I would be grateful for any pointers to fix this!
