https://github.com/JuliaPy/PythonCall.jl/blob/0a7d49f274147e9876fee47981d9aa5459f6eb8c/pysrc/juliacall/__init__.py#L160C44-L160C54 ?
**Describe the bug**
PYTHON_JULIACALL_BINDIR not effective. It still tries to connect the internet and install julia?


**Your system**
linux centos 7

**Additional context**
Add any other context about the problem here.

Start with pysrc/juliacall/__init__.py at the linked location around line 160 and trace how PYTHON_JULIACALL_BINDIR is read during initialization. Reproduce the report on Linux/CentOS 7 with the variable set, checking whether the package still attempts internet access or Julia installation. Done means the configured bindir is honored without those attempts.
