Trying to build ipython 2.2.0 with the doc flag results in:

!!! The ebuild selected to satisfy "dev-python/ipython" has unmet requirements.
- dev-python/ipython-2.2.0::gentoo USE="doc matplotlib notebook qt4 smp -examples -mongodb -nbconvert -octave -test -wxwidgets" ABI_X86="64" PYTHON_TARGETS="python2_7 python3_3 -python3_4"

  The following REQUIRED_USE flag constraints are unsatisfied:
    doc? ( mongodb octave )

  The above constraints are a subset of the following complete expression:
    doc? ( matplotlib mongodb octave ) any-of ( python_targets_python2_7 python_targets_python3_3 python_targets_python3_4 )

Why does there exist this dependency on matplotlib / mongodb / octave? Are all these packages really build time dependencies?

The .ebuild has the following:

        doc? ( dev-python/sphinx[${PYTHON_USEDEP}]
                dev-python/numpydoc[${PYTHON_USEDEP}]
                dev-python/nose[${PYTHON_USEDEP}]
                dev-python/cython[${PYTHON_USEDEP}]
                dev-python/rpy[${PYTHON_USEDEP}]
                $(python_gen_cond_dep 'dev-python/fabric[${PYTHON_USEDEP}]' python2_7)
                >=www-servers/tornado-3.1[${PYTHON_USEDEP}]

So I guess it's the penultimate line that is generating this?

Not a major issue, you can just disable the doc flag, but it would be nice if somebody would clean this up.
