Arch and Orca no module situation

[Linux for blind general discussion]

Hi al,

I downloaded the latest iso of Antergos, it is 18.9 from testing build. 
Orca is included, it has stable Orca and Gnome, but I get this error. NO 
module called pyatspi. I think, this problem was only with Orca master? 
I have the same issue with the current Manjaro Gnome edition after 
installing Orca after install from Dvd. I also installed auto talking 
Arch, and Orca is working here.

Thanks,

Pavel
