What should I do to build a distributions tarball?

[Harries34]

I just simply pulled the code and run ./build-linux.py
and I got a folder at the same dir. 'build/venv.linux', and the python inside is executable
then I tried tar the 'venv.linux' dir. and copied it to another Linux, but the python cannot execute

error code:

./python3

Could not find platform independent libraries <prefix>

Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
