Among other issues, the Apple-supplied 0.9.7 libs for the 10.5 ABI cannot
verify newer SHA-256 certs as now used by python.org services. Document
in the installer ReadMe some of the certificate management issues that
users now need to be more concerned with due to PEP 476's enabling cert
verification by default. For now, continue to use the Apple-supplied
0.9.8 libs for the 10.6+ installer since they use Apple private APIs to
verify certificates using the system- and user-managed CA keychain stores.
Some third-party projects, such as matplotlib and PIL/Pillow,
depended on being able to build with Tcl and Tk frameworks in
/Library/Frameworks. They were unable to build with the built-in
Tcl/Tk and/or execute correctly.
Make it easier for users to make use of the backup _tkinter linked
with the third-party Tcl and Tk frameworks in /Library/Frameworks.
The two tkinter variants are now installed in separate directories
under a new lib-tkinter. This allows per-user selection by
manipulating sys.path, directly or with PYTHONPATH. If this
proves useful, we can supply a more convenient user interface
to supply the paths. For now, this remains somewhat experimental.

of OPT for special build options. By setting OPT, some compiler-specific
options like -fwrapv were overridden and thus not used, which could result
in broken interpreters when building with clang.
64-bit/32-bit installer for 10.6+. It is no longer necessary
to install a third-party version of Tcl/Tk 8.5 to work around the
problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
and later releases.

- Remove OS X installer and Mac/Makefile dependencies on /Developer which
no longer exists with Xcode 4; the referenced tools have been installed
into the usr/bin tool root since Xcode 3.
- Support adding the SDK usr/bin tool root to the installer's PATH via the
SDK_TOOLS_BIN environment variable.
different parsing of the Makefile by distutils.sysconfig and
sysconfig in the case when an intermediate config vars, used to
construct PY_CFLAGS or PY_LDFLAGS, has a trailing space character.
In this case, the OS X installer build script was leaving a
trailing space in the OPT and LDFLAGS config vars. The space is not
significant and it's not worth toying with the Makefile parsing.
build paths from configuration variables cached in _sysconfigdata.py, as
is already done for the installed Makefile. This avoids a distuils test
case failure in test_ldshared_value.
properly skip uncompilable files and to compile existing
files in site-packages if reinstalling. Also, no longer
attempt to install a documentation link in /Developer
as that no longer necessarily exists with Xcode 4.3+.
installer package from the OS X Makefile for Python 3. It has
never worked on Python 3 and is not needed there as pre-10.3.9
installs are no longer supported.
