mac install

[Thomas Nelson]

I downloaded the 3.1.1 dmg from http://www.python.org/download/releases/3.1.1/
but when I run it I get the error "The folowing install step failed:
run postflight script for python documentation." The bugs list has
this bug at http://bugs.python.org/issue6934 but it's described as
fixed. Is it only fixed for the source version? Where should I go to
install?

Thanks,
Tom

Hello. The answer is, I don't know. But I originally replaced my
existing Python with 3.1.1. I then had to backtrack because some stuff
broke. Nothing in the OS, but adapting every Python script on my HD
was not what I wanted to do.

So my Py3 executable is at:
/Library/Frameworks/Python.framework/Versions/3.1/bin/python3.1
then symlink to that in folder:
/usr/local/bin

using command:
sudo ln -s /Library/Frameworks/Python.framework/Versions/3.1/bin/
python3.1 /usr/local/bin/python3.1

so that saying:
ls /usr/local/bin

shows the link to the Py3 folder as:
python3.1 -> /Library/Frameworks/Python.framework/Versions/3.1/bin/
python3.1

Now your existing scripts still work on Py 2.6. New scripts invoke Py3
like this:
#!/usr/local/bin/python3.1

For Terminal sessions, an alias in your bash_profile puts you in Py3
by default without nasty surprises:
alias python=/usr/local/bin/python3.1

You can also create a file at:
/Library/Python/3.1/site-packages/sitecustomize.py

with a configuration that runs at loadtime, although some things seem
to fail. But all in all this system has worked well for me (including
CGI) and should be easy to go mainstream once Apple goes to Py3.

Unfortunately, there hasn't been a release of Python 3.1 since 3.1.1.
On the other hand, the problem isn't critical: it only prevents the
installation from creating the .pyc compiled byte-code files for the
python files in the standard library. Python 3.1.1 should run just
fine, albeit sometimes a bit slower, without them.
