Short version: OS 10.3 (pre 3.9) users are being officially and
wrongly advised to install a 10.4-and-later package that breaks their
stock Python
Long version:
The Python on the Mac download page
(http://www.python.org/download/mac/)
correctly recognizes the under-the-hood kinship of OSX 10.3.9 with
10.4, giving one upgrade link for those versions. It also seems to
recognize the differences between them on the one hand and pre-10.3.9
versions of 10.3 on the other, when it covers the "Panther" case in a
separate paragraph. It suggests a two step installation process
beginning with TclTkAqua, followed by a different link to an updated
Python (Universal-MacPython-2.4.3-2006-04-07.dmg)
The PROBLEM seems to be that this is bad advice. I followed it with my
10.3.7 system and got a (classic, as it turned out) error:
dyld:
/Library/Frameworks/Python.framework/Versions/2.4/Resources/Python.app/
Contents/MacOS/Python can't open library: /usr/lib/libstdc++.6.dylib
(No such file or directory, errno = 2)
Trace/BPT trap
It seems libstdc++.6.dylib was never a part of the earlier OS releases,
and the lack of it is apparently the classic manifestation of
application version incompatibility across the surprisingly wide divide
circa-10.4. In other words, the offered 2.4.3 release (not so much
python itself, I guess, as a couple of Mac apps associated with this
package) seems to have a "10.4 or later" requirement.
Shouldn't the community act promptly to fix this problem (or at least
stamp out this frustrating, time-wasting misinformation?) Anyone know
who to call?
