These are the packages that would be merged, in order:

 

Calculating dependencies... done!

 

!!! Multiple package instances within a single package slot have been pulled

!!! into the dependency graph, resulting in a slot conflict:

 

dev-lang/perl:0

 

  (dev-lang/perl-5.34.1-r3:0/5.34::gentoo, ebuild scheduled for merge) USE="gdbm -berkdb -debug -doc -ithreads -minimal -quadmath" pulled in by

    (no parents that aren't satisfied by other packages in this slot)

 

  (dev-lang/perl-5.30.3:0/5.30::gentoo, installed) USE="berkdb gdbm -debug -doc -ithreads" pulled in by

    dev-lang/perl:0/5.30= required by (dev-perl/Locale-gettext-1.70.0:0/0::gentoo, installed) USE=""

                 ^^^^^^^^

 

app-arch/xz-utils:0

 

  (app-arch/xz-utils-5.2.5-r2:0/0::gentoo, ebuild scheduled for merge) USE="extra-filters nls (split-usr) -static-libs -verify-sig" pulled in by

    (no parents that aren't satisfied by other packages in this slot)

 

  (app-arch/xz-utils-5.2.5:0/0::gentoo, installed) USE="extra-filters nls (split-usr) threads -static-libs" pulled in by

    app-arch/xz-utils[threads] required by (app-arch/libarchive-3.5.1:0/13::gentoo, installed) USE="acl bzip2 e2fsprogs iconv lzma threads xattr zlib -blake2 -expat -libressl -lz4 -lzo -nettle -static-libs -zstd"

                      ^^^^^^^

    sys-libs/ncurses:0/6=[unicode] required by (sys-process/htop-3.0.2:0/0::gentoo, installed) USE="unicode -openvz -vserver"

                          ^^^^^^^

 

 

!!! 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-perl/Locale-gettext-1.70.0:0/0::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.

 

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

page or refer to the Gentoo Handbook.

 

 

The following USE changes are necessary to proceed:

 * In order to avoid wasting time, backtracking has terminated early

 * due to the above autounmask change(s). The --autounmask-backtrack=y

 * option can be used to force further backtracking, but there is no

!!! All ebuilds that could satisfy ">=dev-util/meson-0.59.4" have been masked.

!!! One of the following masked packages is required to complete your request:

- dev-util/meson-9999::gentoo (masked by: EAPI 8)

- dev-util/meson-0.62.2::gentoo (masked by: EAPI 8)

- dev-util/meson-0.62.1::gentoo (masked by: EAPI 8)

- dev-util/meson-0.61.4-r2::gentoo (masked by: EAPI 8)

- dev-util/meson-0.60.3::gentoo (masked by: EAPI 8)

 

The current version of portage supports EAPI '7'. You must upgrade to a

newer version of portage before EAPI masked packages can be installed.
