[gentoo-science] Strange scipy-0.12.0 dependencies

[Jan Marten Simons <marten@xtal.rwth-aachen.de>]

Hi sci,

While trying to update my installation I got a rather strange result, which I 
cannot really make any sense of:

# emerge -avt scipy

These are the packages that would be merged, in reverse order:

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy "virtual/python-
imaging[python_targets_python2_5(-)?,python_targets_python2_6(-)?,python_targets_python2_7(-)?,python_targets_python3_2(-)?,python_targets_python3_3(-)?,-
python_single_target_python2_5(-),-python_single_target_python2_6(-),-
python_single_target_python2_7(-),-python_single_target_python3_2(-),-
python_single_target_python3_3(-)]".
!!! One of the following packages is required to complete your request:
- sci-libs/scipy-0.12.0::gentoo (Change USE: -python_targets_python3_2 -
python_targets_python2_7, this change violates use flag constraints defined by 
sci-libs/scipy-0.12.0: 'any-of ( python_targets_python2_5 
python_targets_python2_6 python_targets_python2_7 python_targets_python3_2 
python_targets_python3_3 )')
(dependency required by "sci-libs/scipy-0.12.0" [ebuild])
(dependency required by "scipy" [argument])

I wonder what might be wrong here. Any idea on this?

Thanks,
Jan


p.s.:
