[Python-Dev] Can not pass configuration on mac os

Hi, I am new here wishing to contribute to python. I tried to go through the tutorial for seting up Cpython, while I cannot pass the configuration. My system is Mac OS and I have installed the command tool of Xcode and hg. But on terminal it said that no such file or directory when I type “./configure --with-pydebug”. What was wrong with my action? How can I fix the issue? This may a little question, but thanks for your help and tutoring! Sincerely, Chongzhao Mao
