unable to reproduce yet, can you try:

INKSCAPE_PROFILE_DIR=~/.config/inkscape PYTHONPATH=/usr/share/inkscape/extensions:/usr/share/inkscape/extensions/inkex/deprecated-simple python3 /usr/share/inkscape/extensions/inkman/inkman/manage_extensions.py

I lost the drive on the previous gentoo install, so this is relatively fresh:

russell@apollo ~ $ INKSCAPE_PROFILE_DIR=~/.config/inkscape PYTHONPATH=/usr/share/inkscape/extensions:/usr/share/inkscape/extensions/inkex/deprecated-simple python3 /usr/share/inkscape/extensions/inkman/inkman/manage_extensions.py

ok, please run following command:

# qfile /usr/share/inkscape/extensions/inkman/inkman/manage_extensions.py
# equery check media-gfx/inkscape
# equery check numpy
# which python3
# cat /var/db/pkg/media-gfx/inkscape-*/RDEPEND
# python3 -V
# python3 -c "import numpy; print('ok');"

Thanks! This bug can be closed. 

The issue was my use of different versions of python for venv's with which I was playing.

Just in case someone runs into a similar issue:

You can specify the python interpreter for extensions in the:

~/.config/inkscape/preferences.xml

file. 

In my case I have put:

<group
     id="extensions"
     org.inkscape.output.png.inkscape.png_bitdepth="99"
     org.inkscape.output.png.inkscape.png_compression="6"
     org.inkscape.output.png.inkscape.png_antialias="2"
     python-interpreter="/usr/bin/python3.12"
     org.ekips.filter.gears.unit="px"
     org.ekips.filter.gears.__live_effect__="0" />


Hope this helps!
