On Gentoo, you can set the EPYTHON environment variable. floppym@naomi ~ % python --version Python 3.6.6 floppym@naomi ~ % export EPYTHON=python2.7 floppym@naomi ~ % python --version Python 2.7.15

I can't tell if by "set it up" to have Python binaries available for only one user, or if you want one user to use a different Python version from other users, with multiple Python versions potentially available to all users, which would be then "Gentoo way". If you have, for example, Python 2.7 and 3.6 installed, you can use "eselect python set ..." to configure the default Python for most users. For individual users, I recommend a Python virtual environment. You can use the 'virtualenv' module for both Python 2.7 and 3.x, but since Python 3.5 the built-in 'venv' module is recommended. I know soft links to a specific Python version were recommended here, but based on my experience I strongly discourage that. Your special user will need more than just the binaries, and a venv is definitely the more robust and versatile way to go. -Ralph

(Thanks to Alexander Kapshuk for the tip.) So, libebml should be added to the list of packages that have to be recompiled with gcc-7.3 (namely, to libtool and llvm), and recompiling everything twice after updating major version of gcc does not seem to be so bad idea for me any more. :)

You're right, I forgot that my stable boxes got hit too. Any idea when the incompatible package ebuilds will be sorted out on the stable tree so we can move onto 3.6 properly?

[gentoo-user] whats going on with python versions?
In my last update which was about June 21 or so, lots of packages were reinstalled to make python3.6 the default target for python3. I don't have any targets like that in my make.conf, so it was done -- about 200 reinstalls. Now when I look at my latest update, a lot of them are going back to 3.5 instead. What is going on here -- are the devs a bit too hasty or what? I am on the unstable, but this is rediculous.
