[Pythonmac-SIG] Re: Python installer results.

Kelvin,
I'm sending my reply to the whole list, because your problem has me
baffled. Let's see whether anyone else can shed some insight.

What appears to be happening here is that it tries to install
PythonCore in the wrong folder. It should put it into
/Library/CFMSupport but it tries to put it in
/System/Library/CFMSupport. This directory is unwriteable for mere
administrators, because it contains Apple's stuff. You might be able
to write it as root, but this is not a good idea.

For me everything worked fine (also 10.0.0 as admin user).

The only thing that I can imagine is that FindFolder has changed
between 10.0.0 and 1.0.1 and now it does not create the
/Library/CFMSupport folder... Nope, just tried it, it does create it
nicely.

Hmm, maybe FindFolder fails for some unknown reason on your system.
Could you try the following:
>>> import macfs
>>> import MACFS
>>> vrefnum, dirid = macfs.FindFolder(MACFS.kLocalDomain,
	     MACFS.kSharedLibrariesFolderType, 1)
>>> fss = macfs.FSSpec((vrefnum, dirid, 'dummy'))
>>> print fss.as_pathname()
