That was exactly the trouble. Somewhere in the build guide this should highlighted under Perl
Dependencies. The other part is that it should describe the proper cpan commands.

I basically ended up with my permissions modified on cpan. I fixed this and then I had to
upgrade LWP::UserAgent

The building guide needs to be oriented towards a rather neophyte developer.

Already we getting the guides lined up with the README.

Having clear update LWP::UserAgent instructions for those who don't know cpan would be enough.
