The E (extension) line in pygimp.interp prints the following warnings:
GIMP-Warning: Bad interpreter referenced in interpreter file /nix/store/5c91dah385gn70blsn6i5rzncqj3ks0y-gimp-with-plugins-2.10.18/lib/gimp/2.0/interpreters/pygimp.interp: python2
GIMP-Warning: Bad binary format string in interpreter file /nix/store/5c91dah385gn70blsn6i5rzncqj3ks0y-gimp-with-plugins-2.10.18/lib/gimp/2.0/interpreters/pygimp.interp
This means that the py extension will not be registered when python2 is not in PATH. To prevent this, let’s hardcode the absolute python2 path.

GIMP uses python interpreter specified in pygimp.interp file for running Python plug-ins,
so any Python related wrapping is useless. It will pick up and use the python from build PATH.
Let’s use a python environment containing pygtk, which is needed by many plug-ins.

It produces an error:
