Bugzilla Bug 183977

src_unpack() {
        unpack ${A}
        cd "${S}"

        sed -i \
                -e '/extras_require/, /},/d' \
                setup.py || die "sed failed"
}
breaks genshi on python-2.5 in the following manner:
Genshi-0.4.2-py2.5.egg-info # cat entry_points.txt 

    [babel.extractors]
    genshi = genshi.filters.i18n:extract[i18n]

    [python.templating.engines]
    genshi = genshi.template.plugin:MarkupTemplateEnginePlugin[plugin]
    genshi-markup = genshi.template.plugin:MarkupTemplateEnginePlugin[plugin]
    genshi-text = genshi.template.plugin:TextTemplateEnginePlugin[plugin]

with the portage ebuild there is no feature called plugin, because of the sed
expression, which removes the requires. This breaks at least turbogears with
python-2.5 (tg-admin just spits that the feature plugin does not exists in
Genshi). Removing the whole src_unpack leads to a correct requires file:

[i18n]
Babel>=0.8

[plugin]
setuptools>=0.6a2

and tg-admin works. So the question is, is this sed at all needed on
python-2.4, and if yes probably stop running it on python-2.5.

Thanks for the report, Gergan.

The seds are all being removed as they are no longer needed due to a change in
setuptools. Fixed in genshi-0.4.2-r1
