[Pythonmac-SIG] Minimal Install Results

So to see exactly what is available on a "minimal" install (no
optional packages at all), I installed a minimal Jaguar install to a
spare partition.
Python.framework is installed, but it contains nothing useful:
[Library/Frameworks/Python.framework] gandreas% ls -lR

-rw-r--r-- 1 root wheel 154270 13 Sep 2003 CoreGraphics.pyo
On the more annoying side, in /usr/bin we get:
[OSX3/usr/bin] gandreas% ls -l py*
-rwxr-xr-x 1 root wheel 44 13 Sep 2003 pydoc*
lrwxr-xr-x 1 root wheel 9 5 Oct 2003 python@ -> python2.3
lrwxr-xr-x 1 root wheel 72 5 Oct 2003 python2.3@ ->
../../System/Library/Frameworks/Python.framework/Versions/2.3/bin/python
lrwxr-xr-x 1 root wheel 10 5 Oct 2003 pythonw@ -> pythonw2.3
-rwxr-xr-x 1 root wheel 122 8 Jun 2003 pythonw2.3*
So the net result is even worse than expected - there is
/usr/bin/python installed, but it can't be run (since there is no
interpreter in the framework), and the framework doesn't contain the
shared library.
So if you test for the existance of /usr/bin/python before running a
script, that won't work. If you embed python using the shared
framework, it probably won't even launch correctly since the shared
binary isn't there. So Bob's careful safety net for PyObjC won't
work either unless you make sure to weak-link the framework (I'm not
sure how doable that is, since I though weak-linking was on a
per-symbol basis, so all the symbols for Python would need to be
weak-linked).
