This is really strange. It actually reports that cysignals is found:
Running command: /home/grhkm/miniforge3/envs/sage-dev-2/bin/python3.11 -c
'import cysignals
print(cysignals.__file__.replace('"'"'__init__.py'"'"', '"'"''"'"'))'
--- stdout ---
/home/grhkm/miniforge3/envs/sage-dev-2/lib/python3.11/site-packages/cysignals/
--- stderr ---
Can you please verify that this folder does contain a "memory.pxd" file.
Another possible solution: try to change the python code around line 25 in
src/meson.build to find cysignals to the following (which should give you
/home/grhkm/miniforge3/envs/sage-dev-2/lib/python3.11/site-packages
in the log file)
import cysignals
import os
print(os.path.dirname(os.path.dirname(cysignals.__file__)))
