Hello, I'm getting this error when installing gazebo via yay, paru, or using makepkg -si

I'm using Arch Linux with kernel 6.6.17-1-lts

Hello,

I've found a workaround for this error. The issue is related to the version of Graphviz being used. The version of graphviz in pacman is version 10, but gazebo is compatible with version 9. Below are the detailed steps I followed to resolve the issue:

I started by removing the version of graphviz that was currently installed on my system. I did this by executing the following command in the terminal:

sudo pacman -Rns graphviz

Then, I cloned the graphviz version 9 package repository from Arch Linux's GitLab. For this, I used the following command:

git clone https://gitlab.archlinux.org/archlinux/packaging/packages/graphviz.git

Inside the cloned repository directory, I checked out to the specific 9.0.0-1 version of graphviz by executing:

git checkout eabf65842071603878f55c7e5d7bedfdf8144658

With the correct version of the graphviz source code in the directory, I proceeded with compilation and installation using makepkg with the command:

makepkg -si

After successfully installing the correct version of graphviz, I attempted to install Gazebo again through the AUR using makepkg -si command. This time, the installation process completed without the previous compilation errors.
