O módulo WWW::Mechanize Perl não será instalado no servidor

Estou tentando descobrir por que um módulo Perl não será instalado no meu servidor.

cpanm WWW::Mechanize

Ele processa coisas por eras e, eventualmente, morre com:

root@admin:~# cpanm WWW::Mechanize
--> Working on WWW::Mechanize
Fetching http://www.cpan.org/authors/id/O/OA/OALDERS/WWW-Mechanize-1.90.tar.gz ... OK

! Installing WWW::Mechanize failed. See /root/.cpanm/work/1543994046.20570/build.log for details. Retry with --force to force install it.

Eu vejo isso lá, mas não tenho certeza do que significa:

#   Failed test '... and it was recorded in the history'
#   at t/history.t line 131.
#          got: '3'
#     expected: '2'

Alguma sugestão? Preciso deste módulo para outro módulo que estou tentando instalar :/
