Thinking about that a bit more, I realised I was misremembering - the
bug was in the way "conda env" activation scripts worked, not in the
initial installation of Anaconda.
So those activation scripts and the equivalent ones for virtualenv and
venv are worth a look for understanding how to configure a currently
active shell session (which is shell dependent), while venv management
tools like vex and pew show how to launch a new subshell with a
reconfigured environment (which is easier to make shell independent
and portable across platforms).
What we don't currently have is anything which makes it easy to set up
a shell session where you're still using the system Python, but "pip
install" is targeting your user site-packages directory (regardless of
the system-wide default behaviour - this is the default on Debian &
Ubuntu for example, but not yet the default on Fedora et al), and you
can run scripts from "~/.local/bin" (this is the default on Fedora,
but not on Debian and Ubuntu, and not necessarily on Fedora
