On behalf of the FreeBSD python team, I'd like to announce that the
lang/python port has been removed as an implicit port dependency for
ports using USE_PYTHON, USE_PYTHON_BUILD and USE_PYTHON_RUN in revision
The removal is necessary to bring us a step closer to building and
installing ports for multiple python versions at the same time.
What does that mean for port users?
If you are using the ports tree to build your own ports from scratch,
propably not much. Chances are high that lang/python was installed
earlier, either as dependency or directly by you. In that case, it is
very unlikely that you will run into any trouble with the change and
hence you should not need to do anything in special.
What does that mean for pkg users?
If you are using pkg or are running your own pkg build server
(e.g. via poudriere), it might happen that the one or other port
breaks, since it cannot find the 'python' command or something
else, which is installed by lang/python.
We tried our best to keep the breakage as low as possible, but with
more than 24000 ports to test and endless OPTION combinations, this is
an impossible task. Please accept our apologies for your inconvenience
and let us know about that misbehaviour by submitting a PR.
If you are not a port maintainer, committer or developer, you can stop
What about maintainers and port developers?
Please read the CHANGES. Keep the direct usage of lang/python within
BUILD_ and RUN_DEPENDS as low as possible. Using lang/python as
dependency will complicate package building for different python
versions (due to the PACKAGE_DEPENDS_ONLY knob). Ports should refer to
a specific python version, version range or a version meta port
(lang/python2 or lang/python3) instead.
USE_PYTHON=yes and friends will only pull in the default python
version now (e.g. lang/python27 or whatever is configured via
DEFAULT_VERSIONS), so test your port thoroughly for (a possibly)
incorrect usage of the 'python' command.
