Hi Alan,

I grepped-r through /etc for  PYTHON_TARGETS and found this:
make.conf:PYTHON_TARGETS="python2_7"

Then I grepped-r rthrough /etc for pulseview and found:
./portage/package.use/pulseview:sci-electronics/pulseview-0.3.0 python_single_target_python3_4 qt5

Nonetheless emerge pulseview still says:
Calculating dependencies \

!!! Problem resolving dependencies for sci-electronics/pulseview                                          ... done!

!!! The ebuild selected to satisfy "sci-electronics/pulseview" has unmet requirements.
- sci-electronics/pulseview-0.3.0::gentoo USE="decode qt5 -qt4 -static" ABI_X86="64" PYTHON_TARGETS="-python3_4"

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

  The above constraints are a subset of the following complete expression:
    decode? ( python_targets_python3_4 ) exactly-one-of ( qt4 qt5 )

[1]    10905 exit 1     emerge sci-electronics/pulseview

Which is overriding the setting via package.use/<file> here?

Cheers
