Last year (2019) I spent a few rather frustrating weeks trying to compile wxPython (Phoenix) for python 3 in 15.1 all by myself … and failing miserably. I admit I am not an expert, but not I am not completely ignorant either. It was just a very hard thing to do. I abandoned the matter in frustration. just checked today and found the experimental pre-built package. Installed fast and worked without problems. To whomever packaged this: THANK YOU! Hats off and again, thank you!
