Checking whether SageMath should install SPKG python3...
checking whether any of bzip2 xz libffi is installed as or will be installed as SPKG... no
checking for python3 >= 3.6.0, < 3.10.0 with modules sqlite3, ctypes, math, hashlib, crypt, readline, socket, zlib, distutils.core... 
checking ... whether /opt/conda/bin/python3 is good... no, this is a misconfigured Python whose sysconfig compiler/linker flags contain -I or -L options, which may cause wrong versions of libraries to leak into the build of Python packages - see https://github.com/sagemath/sage-prod/issues/31132; to use it anyway, use ./configure --with-python=/opt/conda/bin/python3

configure: to try to use a different system python, use ./configure --with-python=/path/to/python
configure: no suitable system package found for SPKG python3
