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 2.3+ .
Version ranges can also be specified, by separating two version
numbers with a dash, e.g.: 2.1-2.3 |
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 2.3. Set
ZOPEBASEDIR containing a directory with
Zope installation. |
