Thanks for this info. I wasn't sure about what is best to use in
'DEPENDS' lines.

Do I understand it right, that '${PYTHON_PKGNAMEPREFIX}feedparser>0'
tests directly, if the port py27-feedparser is installed and
'${PYTHONPREFIX_SITELIBDIR}/ would test, if the file
'' exists in the path '${PYTHONPREFIX_SITELIBDIR}'? (better

In PH, chapter 6.14, three cases are mentioned:

Used as a PKGNAMEPREFIX to distinguish packages for different Python
versions. Example: py24-

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.

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
