What did I miss? I'm new to Arch, so maybe I failed to do something obvious. I was a Gentoo user and I know that python configuring is not always trivial. Maybe something should have been done after installing the packages? I checked that there is no WiKi page for wxpython, and the python page doesn't help. Neither does googling...
