11 Yes, if you need a particular python version for a package and you set e.g.:
12
13 USE="python_targets_python3_4" emerge -1aNDv <package>
14
15 a large number of dependencies will be also rebuilt with python-3.4, which is
16 a pain. If you change the above to "python_targets_python3_5" the whole thing
17 repeats itself, which is a pain. The alternative is to exclude said package
18 and wait a few days until net-misc/electrum (or in my case libreoffice-bin and
19 gdb) ebuilds are updated for the latest stable python.
