As of 2.7.8, the 32-bit-only installer will support OS X 10.5
and later systems as is currently done for Python 3.x installers.
For 2.7.7 only, we will provide three installers:
the legacy deprecated 10.3+ 32-bit-only format;
the newer 10.5+ 32-bit-only format;
and the unchanged 10.6+ 64-/32-bit format.
Although binary installers will no longer be available from
python.org as of 2.7.8, it will still be possible to build from
source on 10.3.9 and 10.4 systems if necessary.
requires them. Disable executable bits and shebang lines in test and
benchmark files in order to prevent using a random system python, and in
source files of modules which don't provide command line interface.
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.
_Qdoffs when compiling with an SDK of 10.7 or later. The OS X APIs they
wrap have long been deprecated and have now been removed with 10.7.
These modules were already empty for 64-bit builds and have been removed
in Python 3. (Original patch by Ronald Oussoren.)
