It is currently not yet supported to install Python packages for other than
the default Python version.
Recently, changes have been made to the ports infrastructure to allow
installing packages for different (also non-default) versions of Python. Fr=
om
/usr/ports/CHANGES:
20140607:
AUTHOR: mva@FreeBSD.org
New PYTHON_CONCURRENT_INSTALL knob to support the parallel installation
of ports for different python versions.
If set to yes, the knob indicates that the port can be installed for
different python versions at the same time. The port will use a unique
prefix for certain directories using USES=3Duniquefiles:dirs (see the
uniquefiles.mk Uses for details about the directories). Binaries
receive an additional suffix, based on ${PYTHON_VER}.
The values for the uniquefiles USES are set as follows:
UNIQUE_PREFIX=3D ${PYTHON_PKGNAMEPREFIX}
UNIQUE_SUFFIX=3D -${PYTHON_VER}
If the port is installed for the current default python version, script=
s and
binaries in
${PREFIX}/bin
${PREFIX}/sbin
${PREFIX}/libexec
are linked from the prefixed version to the prefix-less original name,
e.g. bin/foo-2.7 --> bin/foo.
But the *package tools* don't support this yet. For one of the reasons see
http://lists.freebsd.org/pipermail/freebsd-questions/2013-November/254304.h=
tml
The pkg and ports team is working on fixing package name conflicts in
the ports tree. Right now packages are identified by their origin in the
ports tree. Both py27-sphinx and py33-sphinx have the same origin,
textproc/py-sphinx, so they conflict.
And /usr/ports UPDATING:
20140307:
AFFECTS: users of devel/py-setuptools dependent ports
AUTHOR: sunpoet@FreeBSD.org
devel/py-setuptools is being used for every python ports (if USE_PYDISTUT=
ILS
defined) since r336553. Due to PKGORIGIN limitation, we cannot build one
python port with python27 and the other with python33 since they require
different setuptools versions which have same PKGORIGIN. With the addition
of py-setuptools{27,32,33}, we could now have py27-foo and py33-bar coexi=
st
in one system.
Note that this is only a short-term solution. It does not help if you need
coexistence of one port with different python versions, e.g. py27-foo and
py33-foo.
So this will be fixed in the future.
