[gentoo-dev] PSA: python-r1.eclass, python-single-r1.eclass, and REQUIRED_USE

A quick reminder for anyone using python-r1.eclass or
python-single-r1.eclass:

These eclasses provide a ${PYTHON_REQUIRED_USE} variable that should
be included in REQUIRED_USE under the same USE conditionals (if any)
that ${PYTHON_DEPS} is included in DEPEND/RDEPEND.

For example, if your ebuild has:

RDEPEND=
python? ( ${PYTHON_DEPS}


then you should also have:

REQUIRED_USE=
python? ( ${PYTHON_REQUIRED_USE} )


And if your ebuild just has:

RDEPEND=${PYTHON_DEPS}

then you should also have:

REQUIRED_USE=${PYTHON_REQUIRED_USE}

Failure to include these in REQUIRED_USE may cause the eclass to die
very late in the build process.

Thank you,

Jonathan Callen

Thanks for that. I probably should have announced it myself.

Is there actually list of current offenders?

It would be pretty nice to have bugs opened if someone forgot to set it.
