1 I realize just now that one of my machines uses
2 emerge ... --newuse ...
3 and the other uses
4 emerge ... --changed-use ...
5 Both run gentoo stable.
6
7 I imagine this discrepancy has been there for a long while and to date
8 has caused no particular difficulty. However, today the --changed-use
9 machine can't --depclean and running
10 emerge --pretend --newuse ... @world
11 shows 15 rebuilds while --changed-use shows none.
12
13 It looks like all the rebuilds are caused by "negative" uses,
14 especially PYTHON_TARGETS="-python3_6%"
15
16 My first thought was to run an
17 emerge --newuse ... @world
18 and then proceed with --depclean'ing
19
20 but am cautious about changing settings involving python (I have no
21 personal python scripts).
22
23 eselect python show
24 indicates python3.4, which I realize has end of life next year.
25
26 Any advice would be appreciated.

28 Thanks in advance,
