Yes, it is.

And if you do, you can put it in:


(/Library is kind Apple's answer to /usr/local, at least for Frameworks)

What that means is that you need to install a new Python, too. I think 
those notes were for using the Apple-supplied Python. But it's a good 
idea to build your own Python (or install the python.org one) in 
/Library anyway -- Apple has never upgraded a Python within an OS-X 
release, and tends to have a bunch of not-quite-up-to-date pacakges 
installed. Since you don't know which of those packages are being used 
by Apple utilities, and Python doesn't provide a package versioning 
system, and not all package updates are fully backwards compatible, it's 
best to simply not mess with Apple's python at all.
