Description

We need to prompt the user to set DYLD_LIBRARY_PATH

I configured the python environment through conda, and I have set the LLGO_LIB_PYTHON

❯ echo $LLGO_LIB_PYTHON      
/opt/anaconda3/envs/python312env/lib/python3.12
(python312env)

❯ llgo run .
dyld[64794]: Library not loaded: @rpath/libpython3.12.dylib
  Referenced from: <3A4ABF35-C399-30BF-A363-274C7529E109> /Users/zhangzhiyang/go/bin/callpy
  Reason: tried: '/libpython3.12.dylib' (no such file)

When 'DYLD_LIBRARY_PATH' is set, it will run normally

export DYLD_LIBRARY_PATH=/opt/anaconda3/envs/python312env/lib:$DYLD_LIBRARY_PATH

Research direction

Reproduce llgo run . on macOS with a conda Python environment using LLGO_LIB_PYTHON, then inspect the llgo run path that invokes callpy and handles the missing libpython error. Done means users are prompted to set DYLD_LIBRARY_PATH when required, while the command succeeds when that variable is set.
