Installing GD Perl module on Ubuntu 16

I'm trying to get the GD.pm Perl module installed on my server. I get this error when trying to install with cpanm:

Please install libgd 2.0.28 or higher.

I did some research, and people suggest trying to run apt-get install perl-GD, but as you can see from below it doesn't work:

root@mail:~# apt-get install perl-GD
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package perl-GD

I'm a bit stumped as to what else to try. I've already got the GD PHP module installed and working, so I would have thought they would be one and the same thing with the underlying software?

My server is Ubuntu 16.04.2 LTS, with PHP 7 and Perl 5.22.1

Thanks!

Eugh, and as if by magic (AGAIN!). I just found this post:

https://unix.stackexchange.com/questions/324342/how-to-instal-perl-modules-gd-and-gdpolyline-in-debian

...and they suggest running:

apt-get install libgd-perl

Sure enough, that does the job. All working perfectly now. Maybe I should post my questions here first, instead of spending hours searching around, as it seems to be only then I find the answers ;)
