Install Perl Search::Elasticsearch error

Using CPAN to install Search::Elasticsearch, and I'm getting an error, seemingly in the test stages of the install:

Result: PASS
Tests succeeded but one dependency not OK (Cpanel::JSON::XS)
[dependencies] -- NA
Failed during this command:
ETHER/JSON-MaybeXS-1.003005.tar.gz : make_test NO one dependency not OK (Cpanel::JSON::XS)


However, CPAN says Cpanel::JSON::XS is installed successfully:

cpan[6]> test Cpanel::JSON::XS
Running test for module 'Cpanel::JSON::XS'
Running make for R/RU/RURBAN/Cpanel-JSON-XS-3.0211.tar.gz
Has already been unwrapped into directory /myhome/.cpan/build/Cpanel-JSON-XS-3.0211-_9weML
Has already been made
Running make test
Has already been tested successfully

I hope this isn't a noob question.
