Install an up to date version of libgd on your system, then use
cpanto build the perl module GD against it. You haven't specified which OS you are on, if it has a package manager you should be able to install it from there:
sudo pacman -S gd [sudo] password for marto: warning: gd-2.3.3-9 is up to date -- reinstalling resolving dependencies... looking for conflicting packages... Package (1) Old Version New Version Net Change extra/gd 2.3.3-9 2.3.3-9 0.00 MiB
Then just reinstall the module using cpan or otherwise. If on windows see instructions at https://github.com/libgd/libgd, or consider using Strawberry perl with all this sort of thing included.
