[Buildroot] [Bug 7772] libxml-parser-perl build failure: missing dependency ExtUtils/MakeMaker

[Vicente Olivert Riera <Vincent.Riera@imgtec.com>]

Hello Francois,

below are the outputs of the commands you suggested. You said
ExtUtils-MakeMaker comes with the perl installation, but that's not true
for CentOS (I guess RedHat and Fedora as well) and Gentoo.

$ perl -V
