It may be confusing to users as well. If we can get rid of the suffix for PYTHON_CONCURRENT_INSTALL for whichever version is PYTHON_DEFAULT, it should be a net positive to treat it the same way we did USE_GCC in the past (enable PYTHON_NO_CONCURRENT or something and remove it on per-port basis once fixed). - Nikolai Lifanov --mcd4NCjmhD7HuKmBbpNX7oEJtsex8Vsv5-- --DNWIBClh0mU24Cvhhr2unpO00dtEPVbws Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQKoBAEBCgCSFiEE5oT6TcuaWvG5gtjzZ6sv56ecR0UFAliOvohfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEU2 ODRGQTREQ0I5QTVBRjFCOTgyRDhGMzY3QUIyRkU3QTc5QzQ3NDUUHGxpZmFub3ZA ZnJlZWJzZC5vcmcACgkQZ6sv56ecR0WJTQ/9He1FKY6tNzGM8nZn0pr/9SUtsykm eg6Z/OwxgSgV9p5Tkp4kFlPPLzkconVqESJGy9slhLqFjL1CiG8CfzfY0T2S8IrS wC9WEzqxTJ4Zo/DYjynH3+usFLBcCANdA5kpsdUW4RAgRk4D6qLuLfAeAuhvNLkO e5s6oVSwKIZ5Pq0OuTnC3Fqf0dXv7zrxPLh1E8fKEHEKj25LYA15tCUFTLghFTg8 wUWjKa6fQ+Tzjs1nFk4vOfsmVyQigwqCOQbfEyqcEEPS5UHrfwBTjJows+DpqtSX pzFSnSqYvYgWep6/yP1s2mEAjEvwD3Bj3q522fOF4FoQlx2l7Ai6+oA0vvqwzHXJ lL2jmTn96jwXeQ8hP/L7DoqRcjJNykJjz5HebzrCijvW+7DjRyQvTV6in+4SPYgZ jr/lUuRgdYL6cyf/JZliWixVL71Aq2gFE6PBNzF+JZkLcsfQY02PM8nSEm0S52j+ iCoxFlSstUPmqCy4ksgexHxXfyStG5TbBHqamVD2vuZwFOtT5r2xi3RkuWgKzaus f8vcNaQnVnko2+mXN8nsaXHSGs2W5m5YUwlvNeJM6PDkdRNjBDM1WUCffIeAkbiE qo+IjtwnFxb24vyb01L0HWG1Miq4vEy14IMlbzAZNr/CtnZqDnnTQtgoCC3NMaVi z7Xf+Z2q/l6mlLU= =5BwE -----END PGP SIGNATURE----- --DNWIBClh0mU24Cvhhr2unpO00dtEPVbws--
