I don't have Py3 installed at all on all my machines. |

It seems you have no clue how this eclass works. If you have only py3 installed, |
| 31 |
and you set PYTHON_TARGETS="python2_7" then dev-lang/python:2.7 will be added to |
| 32 |
DEPEND and installed. |
| 33 |
|
| 34 |
The user asked to install for py2:7 so he will get this done. It's not a |
| 35 |
usability regression - it's expected behaviour: user wants to build for FOO:X.Y |
| 36 |
then the eclass adds FOO:X.Y to DEPEND. |
| 37 |
|
| 38 |
I fail to see how would you like to "correctly and transparently" (whatever it |
| 39 |
means to you) do it. If you don't accept as a solution an error message or |
| 40 |
pulling in py2:7 then there's no other way - you either install missing |
| 41 |
dependencies or die with an error, no third way. |
