gtk-vnc build error on Slackware64-current

Hello Forum, It's me again. Yeah i've finally decided to install -current as my host after about 2 months running 14.2.

I want qemu-kvm + virt-manager. I had a problem slackbuilding gtk-vnc on 14.2 recently which is solved by building an older version of meson as advised by ponce, build 0.53.0 instead of 0.57.0. It worked like a charm.

It's funny that I am having the same problem aotm. I can not get past building gtk-vnc again. How do i approach this? -current has meson-0.59.0 as of writing.

I know some of our awesome slackers advised on using slackrepo
but I am still learning how to properly set that up. As of now I can say that I am fairly familiar with sbopkg and manually slackbuilding packages.

On 14.2 this is the virt-manager.sqf
