While here: - fix DEBUG build/package (several %%ABI%% were in the wrong place in pkg-plist that caused failed installs) - switch to using system textproc/expat2 library - issue warnings in pre-test that IPV6, PYMALLOC are required and DEBUG also breaks one self-test - bump PORTREVISION - drop LTOFULL again and make LTO use =3Dfull References: =20=20=20 https://mail.python.org/archives/list/security-announce@python.org/thread/H= TWB2Z6KT5QQX4RYEZAFININDHNOSIF3 https://www.cve.org/CVERecord?id=3DCVE-2026-6100 https://github.com/python/cpython/pull/148396 Obtained from: GitHub repo =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 https://github.com/python/cpython/commit/c8d8173c4b06d06902c99ec010ad785a30= 952880 Security: CVE-2026-6100 b8e9f33c-375d-11f1-a119-e36228bfe7d4 --=20 You are receiving this mail because: You are on the CC list for the bug.=
