Description A. Wilcox (awilfox) 2016-04-17 19:36:54 UTC

Installing a Python interpreter using emerge --root succeeds, but during installation, I receive a message such as:

  Switching to python3.5
  Couldn't find a man page for python3.5; skipping.

This is because I have python3.5 installed on the host (in /), but not in the merge root (ROOT=/usr/x86_64-pc-linux-musl in this case).

The get_installed_pythons function of python.eselect should probably be using INTERPRETER_DIR in its type calls.

The eselect python ebuild does this in pkg_postinst:

eselect python update --if-unset

get_installed_pythons() has this:

# filter to installed only
if type -P "${i}" &>/dev/null; then
	echo "${i}"
fi

This is going to give bad results if we are trying to update the selected python with ROOT != /.
