Removing slotted libpng in Gentoo

While upgrading my Gentoo system, I upgraded gentoolkit package and I got a message saying asking me to run the following command.

glsa-check -p affected

Running it told me that there are no upgrades available for libpng-1.2.44. I found out that there were multiple versions of libpng installed on my system:

• libpng-1.4.5 and;
• a slotted version, i.e. libpng-1.2.44.

The solution was to remove all versions of libpng and freshly install it. This can be achieved using the following command.

emerge -C libpng && emerge -1 libpng:0
