The Ports Collection supports parallel installation of
multiple Python versions. Ports should make sure to use a
correct python
interpreter, according to
the user-settable PYTHON_VERSION
variable.
Most prominently, this means replacing the path to
python
executable in scripts with the value
of PYTHON_CMD
variable.
Ports that install files under
PYTHON_SITELIBDIR
should use the
pyXY-
package name prefix, so their package
name embeds the version of Python they are installed
into.
USE_PYTHON | The port needs Python. Minimal required version
can be specified with values such as
2.6+ . Version ranges can also be
specified, by separating two version numbers with a
dash, e.g.: 2.6-2.7 |
USE_PYDISTUTILS | Use Python distutils for configuring, compiling
and installing. This is required when the port comes
with setup.py . This overrides
the do-build and
do-install targets and may
also override do-configure if
GNU_CONFIGURE is not
defined. |
PYTHON_PKGNAMEPREFIX | Used as a PKGNAMEPREFIX to
distinguish packages for different Python versions.
Example: py24- |
PYTHON_SITELIBDIR | Location of the site-packages tree, that contains
installation path of Python (usually
LOCALBASE ). The
PYTHON_SITELIBDIR variable can be
very useful when installing Python modules. |
PYTHONPREFIX_SITELIBDIR | The PREFIX-clean variant of PYTHON_SITELIBDIR.
Always use %%PYTHON_SITELIBDIR%% in
pkg-plist when possible. The
default value of
%%PYTHON_SITELIBDIR%% is
lib/python%%PYTHON_VERSION%%/site-packages |
PYTHON_CMD | Python interpreter command line, including version number. |
PYNUMERIC | Dependency line for numeric extension. |
PYNUMPY | Dependency line for the new numeric extension, numpy. (PYNUMERIC is deprecated by upstream vendor). |
PYXML | Dependency line for XML extension (not needed for Python 2.0 and higher as it is also in base distribution). |
USE_TWISTED | Add dependency on twistedCore. The list of
required components can be specified as a value of
this variable. Example: web lore pair
flow |
USE_ZOPE | Add dependency on Zope, a web application
platform. Change Python dependency to Python 2.7.
Set ZOPEBASEDIR containing a
directory with Zope installation. |
A complete list of available variables can be found in
