Note wxgtk2 and wxgtk3 both provide wxWidgets 3.0.4; the difference is that they are built against GTK 2 and 3 respectively.

The binary golly distribution (which you can download from SourceForge) is built against GTK 2, so if you want to use that one, you need to install wxgtk2. The source distribution can be built against either one, which is why the golly AUR package depends on just wxgtk.

On Arch linux, I would suggest installing the AUR package (which will probably pull in wxgtk2 by default). If that doesn't work, that's a separate problem to be solved; I don't think the solution is to switch to the binary distribution instead.

Please don't rename/symlink libraries in the root filesystem; that's likely to create other problems in the future, and, as you noticed, it usually doesn't work anyway. It's almost certainly the wrong solution to your problem.
