Created attachment 385586 [details] emerge --info hugin Looking at the source suggests this is an issue with calling: python-single-r1_pkg_setup Regardless of the value of USE=python My PYTHON_* flags are indeed a bit nonsense, but I'm weeding out some things and this problem should ideally fail at dependency resolution, or not fail at all: [ebuild R ] media-gfx/hugin-2014.0.0_rc4 USE="-debug -lapack -python -sift" LINGUAS="en_GB -cs -da -de -es -eu -fi -fr -hu -it -ja -nl -pl -pt_BR -ro -ru -sk -sv -zh_CN -zh_TW" PYTHON_SINGLE_TARGET="python3_3 -python2_7 (-python3_2)" PYTHON_TARGETS="-python2_7* (-python3_2) -python3_3*" 0 KiB Looking at the REQUIRED_USE looks like its doing the right thing: > /usr/portage/metadata/md5-cache/media-gfx/hugin-2014.0.0_rc4 REQUIRED_USE=python? ( python_single_target_python2_7? ( python_targets_python2_7 ) python_single_target_python3_2? ( python_targets_python3_2 ) python_single_target_python3_3? ( python_targets_python3_3 ) ^^ ( python_single_target_python2_7 python_single_target_python3_2 python_single_target_python3_3 ) ) So had USE=python been set, it would have failed correctly. So it just looks like it needs: - python-single-r1_pkg_setup + use python && python-single-r1_pkg_setup Applying that made it work for me.
Well, "work". Seems I spoke too soon. * Call stack: * ebuild.sh, line 93: Called src_install * environment, line 3627: Called python_optimize * environment, line 3361: Called die * The specific snippet of code: * [[ -n ${EPYTHON} ]] || die 'No Python implementation set (EPYTHON is null).'; Seems to need: - python_optimize + use python && python_optimize Too.

Fixed in cvs, thanks for the report and ebuild! 27 Sep 2014; Markus Meier <maekke@gentoo.org> hugin-2014.0.0_rc4.ebuild: call python eclass functions depending on USE=python, by Kent Fredric in bug #523842
