Sure, so Pex is trying to create a venv and it's running:
Copy code
/Users/szto/.pyenv/versions/3.9.15/bin/python -m ensurepip -U --default-pip
That apparently hangs. Can you try running that manually?

Copy code
➜  linear-cli git:(main) ✗ /Users/szto/.pyenv/versions/3.9.15/bin/python -m ensurepip -U --default-pip            
Looking in links: /var/folders/4y/2r8ypdnx6kv0t1vd71t6kd1h0000gn/T/tmpltwei0db

I ran the script but it is the same running export command

For full fidelity, try:
Copy code
/Users/szto/.pyenv/versions/3.9.15/bin/python -mvenv pex.venv
pex.venv/bin/pip install pex==2.1.111
pex.venv/bin/pex -o empty.pex --include-tools
PEX_TOOLS=1 ./empty.pex venv test.venv --pip

Ok then, you have a good narrow case to dig on. I have no clue why it hangs.
Sometimes folks have a borked interpreter. You could try
pyenv install 3.9.16
and see if that interpreter has the same issue or not.
