Python single_target target abis

[hlaube]

I have a problem with the settings for python.

 

I want to use libreoffice, digikam and util-linux, all want to have python.

 

Without any settings in make.conf,  lensfun does not like me. but libroffice and util-linux are fine

!!! The ebuild selected to satisfy "media-libs/lensfun" has unmet requirements.
- media-libs/lensfun-0.3.2::gentoo USE="-doc -test" CPU_FLAGS_X86="sse sse2" PYTHON_SINGLE_TARGET="python3_3 python3_4 -python3_5" PYTHON_TARGETS="python3_3 -python3_4 -python3_5"

  The following REQUIRED_USE flag constraints are unsatisfied:
    exactly-one-of ( python_single_target_python3_3 python_single_target_python3_4 python_single_target_python3_5 ) python_single_target_python3_4? ( python_targets_python3_4 )

  The above constraints are a subset of the following complete expression:
    exactly-one-of ( python_single_target_python3_3 python_single_target_python3_4 python_single_target_python3_5 ) python_single_target_python3_3? ( python_targets_python3_3 ) python_single_target_python3_4? ( python_targets_python3_4 ) python_single_target_python3_5? ( python_targets_python3_5 )

Setting

PYTHON_ABIS="2.7  3.4"

does not make any difference.

 

Since lensfun wants an minimum python 3.3 I tried  in my make.conf 

PYTHON_SINGLE_TARGET="python3_3"

 

Now libreoffice is not satisfied, but lensfun and util-linux like me

( java ) libreoffice_extensions_wiki-publisher? ( java )

Setting in the make.conf

 

PYTHON_SINGLE_TARGET="python3_4"
PYTHON__TARGET="python3_4"

results into success with libreoffice and lensfun, but util-linux does not play

  The following REQUIRED_USE flag constraints are unsatisfied:
    python? ( python_single_target_python3_4? ( python_targets_python3_4 ) )

  The above constraints are a subset of the following complete expression:
    python? ( exactly-one-of ( python_single_target_python2_7 python_single_target_python3_3 python_single_target_python3_4 ) python_single_target_python2_7? ( python_targets_python2_7 ) python_single_target_python3_3? ( python_targets_python3_3 ) python_single_target_python3_4? ( python_targets_python3_4 ) )

I also tried two targets into

 

PYTHON_SINGLE_TARGET="python2_7 python3_4"
PYTHON__TARGET="python2_7 python3_4"

 

Does not work with one of the three ether.  I am pretty sure, there is a simple solution, since two days I do not find it.

Thanks, that workaround helped.
