on the "pkgsrc-users" mailing list:
1.) Fix 64-Bit ABI check for Snow Leopard so it doesn't break the build
on older version of Mac OS X.
2.) Properly disable the "pyexpat" module and remove it from the
package list.
Bump package revision because of these changes.

Tests
-----
- Issue #5837: Certain sequences of calls to set() and unset() for
support.EnvironmentVarGuard objects restored the environment variables
incorrectly on __exit__.
* not "_sqlite", but "_sqlite3", fixes PR#42070.
* "bsddb" does not exists. (I can find it in Python21, not in Python23)
* "cjkcodecs" should not be disabled.
It is expected to exists in all Python variants and py-cjkcodecs was removed.
Although, the module name is "_multibytecodec" and "_codecs_*".
and missing "," after it kill subsecuent "gdbm".
* "mpz" was removed in Python24.
earlier, but there became no-ops due to my change to db4/bl3 and thus
didn't do harm. Now that part of that change was backed out they became
harmful again and thus need to go.
on Linux one can't build some extensions against an old Python (with
spurious -ldb4 linkage) anymore
also sync the bl3 files of the non-default versions with python25
for consistency
Compiles, installs, and runs on NetBSD-5.99.10/amd64; no further
tests done. Please test and fix on your platform!
What's new in Python-2.6:
The major theme of Python 2.6 is preparing the migration path to
Python 3.0, a major redesign of the language. Whenever possible,
Python 2.6 incorporates new features and syntax from 3.0 while
remaining compatible with existing code by not removing older
features or syntax. When it tries to do what it can, adding
compatibility functions in a future_builtins module and a -3 switch
to warn about usages that will become unsupported in 3.0.
Some significant new packages have been added to the standard
library, such as the multiprocessing and json modules, but there
aren way.
Python 2.6 also sees a number of improvements and bugfixes throughout
the source. A search through the change logs finds there were 259
patches applied and 612 bugs fixed between Python 2.5 and 2.6. Both
figures are likely to be underestimates.
