in thread Upgrading XS module to later version

I ran into the same problem, when trying to install cpan Moose, it says that 
Installing the dependencies failed: Installed version (1.55) of List::
+Util is not in range '1.56'

[download]
Trying to install List::Util with cpanm List::Util seems to work, it show the message 
Successfully installed Scalar-List-Utils-1.60 (upgraded from 1.55)

[download]
But when then trying to run cpan Moose it complains again about error 
Installing the dependencies failed: Installed version (1.55) of List::
+Util is not in range '1.56'

[download]
Obviously, cpanm did not upgrade List::Utils. but installed it in a different directory. When I check the installed packages, I get this 
$ cpan -l |grep List::Util
List::Util      1.55
List::Util::XS  1.55
Module::CoreList::Utils 5.20210520
List::Util      1.55
List::Util::XS  1.55
Module::CoreList::Utils 5.20210520
List::Util      1.55
List::Util::XS  1.55
site_perl::List::Util   1.60
site_perl::List::Util::XS       1.60
List::Util      1.60
List::Util::XS  1.60
List::Util      1.60
List::Util::XS  1.60
List::Util      1.55
List::Util::XS  1.55
Module::CoreList::Utils 5.20210520

It is not clear to me how to ensure that the newer version should used.

    do you have multiple perls installed? Are you using perlbrew or local::lib? What does which cpan and which cpanm show?

      Yes, I've multiple versions of perl.
      There are the perl modules from the operation system (in my case Debian 10, or 11, I tested both)
      Then I've compiled Perl 5.32.1 and 5.34.0 from source, and I'm trying to install Moose as part of any of these version.
      The software will be installed as seperate packages on a computing cluster on an nfs-storage.

      I use neither perlbrew nor local::lib, but install from source with 

          
    export PREFIX=/my/install/directory/perl/5.34.0/
    ./Configure -des -Dprefix=$PREFIX \
        -Dusethreads \
        -Duseshrplib  \
        -Dinc_version_list=none
   make -j4 && make test && make install

      [download]
      Once perl is installed, these environment variables are set: 
         export PERL5LIB=$PREFIX/lib
   export PATH=$PREFIX/bin:$PATH
   export MANPATH=$PREFIX/man:$PATH
   export LD_LIBRARY_PATH=$PREFIX/lib:$LD_LIBRARY_PATH

      [download]
      and cpan is installed with 
         curl -L https://cpanmin.us | perl - App::cpanminus

      [download]
      The command " which cpan cpanm " results in displaying the version in 
         $PREFIX/bin/cpan
   $PREFIX/bin/cpanm

        What's the output of 

        which perl
which cpan
which cpanm
head -n 1 "$( which cpan )"
head -n 1 "$( which cpanm )"

      This is solved now. The packages are installed in $PREFIX/lib/site_perl, and I had to set 

       
    PERL5LIB=$PREFIX/lib/site_perl

      [download]

      That seems to fix the issue.

      BTW: the information was quite difficult to find, because I did not see any documentation about that, but had to infer this from "man perlrun ->ENVIRONMENT" and from what cpan(m) is doing.

        Something's wrong with your build of Perl if it doesn't look in its own site lib dir!
