This is the error I am getting (ActivePerl 5.16.3, Windows 10)

That's a problem with the installation of DB_File, not Lingua::EN::NamedEntity. You said earlier you tried on Strawberry Perl, but the release notes indicate that DB_File is already included there as far back as 5.10.1, so what problem did you have there? As for ActivePerl, this page does seem to indicate that there are no PPMs available. It's been way too long since I last used ActivePerl to be able to help there, but I have had good experiences with Strawberry Perl so I would recommend that instead, because it includes all the build tools you need.

thank you for your reply. I tried again with the latest release of Strawberry perl and it worked indeed! With ActivePerl (which is the main version of Perl I use for production) it doesn't install.
