!!! 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:

  (sys-apps/man-db-2.8.7:0/0::gentoo, installed): ebuild is masked or unavailable

  (dev-lang/python-2.7.18:2.7/2.7::gentoo, installed): ebuild is masked or unavailable

  (dev-lang/python-3.7.7-r2:3.7/3.7m::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.

For more information, see MASKED PACKAGES section in the emerge man

page or refer to the Gentoo Handbook.

# Michał Górny , Andreas K. Hüttel ,

# Matthias Maier  (2017-05-21 and later updates)

# These old versions of toolchain packages (binutils, gcc, glibc) are no

# longer officially supported and are not suitable for general use. Using

# these packages can result in build failures (and possible breakage) for

# many packages, and may leave your system vulnerable to known security

# exploits.

# If you still use one of these old toolchain packages, please upgrade (and

# switch the compiler / the binutils) ASAP. If you need them for a specific

# (isolated) use case, feel free to unmask them on your system.

man page or refer to the Gentoo Handbook.
