>Description:
	When running make build-depends-list, the list produced is not always accurate:
	For e.g. www/trac defines BUILD_DEPENDS as:
		BUILD_DEPENDS=  ${PYTHON_SITELIBDIR}/pysqlite2/__init__.py:${PORTSDIR}/databases/py-pysqlite20 \
                ${PYTHON_SITELIBDIR}/neo_cgi.so:${PORTSDIR}/www/clearsilver-python \
                ${PYTHON_SITELIBDIR}/svn/__init__.py:${PORTSDIR}/devel/subversion-python
	
	However:
		starbug:/usr/ports/www/trac# make -VPYTHON_SITELIBDIR
		/usr/local/lib/python2.4/site-packages
		starbug:/usr/ports/www/trac# ls -l /usr/local/lib/python2.4/site-packages/svn/__init__.py
		-rw-r--r--  1 root  wheel  760 25 Nov 13:31 /usr/local/lib/python2.4/site-packages/svn/__init__.py
		starbug:/usr/ports/www/trac# make build-depends-list
		/usr/ports/databases/py-pysqlite20
		/usr/ports/devel/subversion-python
		/usr/ports/lang/python24
		/usr/ports/www/clearsilver-python

	build-depends-list should not display devel/subversion-python as the required file already exists (devel/subversion is installed with WITH_PYTHON). This confuses portmaster as it tries to install devel/subversion-python when it shouldn't.

>How-To-Repeat:
	Install devel/subversion with WITH_PYTHON=yes, and install www/trac using sysutils/portmaster. Portmaster incorrectly identifies devel/subversion-python as a dependency as it relies on build-depends-list.
