Hi Larry,
Yes, it was very much.
Thanks.

Kevin,
If you do a "typical" compile of your own Python from source I would
install it in /usr/local/ bin and lib. If you download an OSX pre-
built Python 2.7.1 (or 3.2) I would let it install itself in /
Library/Frameworks/Python.framework/... (See http://python.org/download/releases/2.7.1/)
Then, be really, really sure all 3rd party packages are installed in
the appropriate site-packages dir. Each version of Python will
likely have its own site-packages and a package installed with one
version of Python will most likely *not* be in the correct site-
packages dir for your most recent Python. Do not assume you can
simply copy a package from one site-packages dir to another as some
packages are built for specific versions of Python.
And finally, be sure your links, aliases and paths will find the
intended version.
As to which root dir location is best, it doesn't really matter as
long as your links, aliases, and paths can find it. Personally, I
have multiple (8) versions installed and use aliases and links to
keep things copesthetic. And to avoid issues when installing
packages, I use the longer, fully qualified pathnames.
I also like reserving /usr/... and /System/Library/Frameworks/
Python.framework/Versions/... for the exclusive use by Apple. I do
not mess with what I find there. It was "factory installed" and I
let only "the factory" modify them. I just make sure my versions
are higher on the search list. (Years ago I had BAD EXPERIENCE [on
RH 4.x IIRC] when I updated the version of Python I found in /
usr/... It seemed safe enough. Let's just say the consequence was
*very* painful.)
So, armed with this I would first check your links, aliases, and
paths. Be sure /usr/local/bin is early in your $PATH. I would
carefully inspect for the *correct* packages in the appropriate site-
packages dir, re-installing as appropriate. Please know that
ElementTree was added to the Python Standard Library as of version
2.5 so you may not want to install another in site-packages. (You
may need to tweak your import statements however.)
I hope this helps,
Larry

Hi Larry + Chris.
Any thoughts on a PPC based Mac running 10.5.8 where is best place
to put Py 2.7.x?
Apple sticks files under /usr/bin
Python sticks files under /usr/local/bin
Most times things has worked so far.
Right now ElementTree is not liking my setup and is blowing up
minidom.
Not sure how or why.
My thought is to wipe all the old PY 2.3, 2.5 and 2.7 files .
And only have the one version of Python 2.7 as this is all I need
on this machine.
Where do you think is the best place to put it?
Or does it not really matter?
I have noticed some developers set code up to look for the stock
apple location.
Any thoughts?
Thanks

Hi All,
Is there any one on the list that is really up on installing new
versions of Python on to the Mac?
And has time to answer a quick question on how best to do this?
Thanks
