NOTE: Use the '--verbose-conflicts' option to display parents omitted above

!!! The slot conflict(s) shown above involve package(s) which may need to
!!! be rebuilt in order to solve the conflict(s). However, the following
!!! package(s) cannot be rebuilt for the reason(s) shown:

  (dev-libs/folks-0.11.4-r1:0/25::gentoo, installed): ebuild is masked or unavailable
  (mail-client/evolution-3.30.5:2.0/2.0::gentoo, installed): ebuild is masked or unavailable
  (gnome-base/gnome-shell-3.30.2-r2:0/0::gentoo, installed): ebuild is masked or unavailable


It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

#/etc/python-exec/python-exec.conf
# python-exec global preference configuration
#
# This file specifies global Python preference for python-exec. It
# determines which implementations will be used when wrapped Python
# scripts or generic Python wrappers (such as /usr/bin/python) are
# started with no implementation override (EPYTHON).
#
# The global configuration can be overriden for each wrapped script
# in /etc/python-exec/<script-name>.conf. If this override exists,
# the global configuration is not used at all.
#
# The preference file should list Python implementations, one per line,
# in EPYTHON-format (e.g. python3.5), in order of preference. The most
# preferred implementation should be listed first. The program will use
# the most preferred implementation that is supported by it.
#
# If none of the listed implementations are supported, python-exec will
# attempt to use the remaining supported implementations in default
# order.
#
# A specific implementation can be disabled by preceding it with
# a hyphen (-). In this case, the implementation will never be used.
# If no other implementation is supported by the program, it will fail
# to start.
#
# Note: this file can be modified by calls to 'eselect python'.
