Thanks for the help, but I still have the problem. |
| 56 |
|
| 57 |
emerge --info showed the same for PYTHON_SINGLE_TARGET="python3_5" and |
| 58 |
PYTHON_TARGETS="python2_7 python3_5" |
| 59 |
|
| 60 |
eix -I python shows 2.7.14 and 3.4.5 on both systems |
| 61 |
|
| 62 |
grep -i python /etc/portage/make.conf |
| 63 |
has no hits on either system |
| 64 |
|
| 65 |
eselect python list showed the same two version (3.4 and 2.7) |
| 66 |
but in *opposite* order. I issued |
| 67 |
eselect python set 2 |
| 68 |
on the failing 7450 and now both report |
| 69 |
Available Python interpreters, in order of preference: |
| 70 |
[1] python3.4 |
| 71 |
[2] python2.7 |
| 72 |
|
| 73 |
I don't believe I need to "activate" this change, right? |
| 74 |
|
| 75 |
However, after making the above change the 7450 still fails to emerge |
| 76 |
update world saying |
