Hello everyone,

I'm very impressed of the Io language, especially the minimal syntax, so 
I wanted to install OpenGL for Io in the addons section on my Arch Linux 
machine, to have an extended working range for Io. But neither Flux nor 
OpenGL worked because of "Exception: Object does not respond to Cairo".
So after a bit of research I uncommented the Cairo addon and it got 
installed, but now I get the error "Exception: Error loading object 
'/usr/local/lib/io/addons/Cairo/_build/dll/libIoCairo.so': 
'/usr/local/lib/io/addons/Cairo/_build/dll/libIoCairo.so: undefined 
symbol: IoState_protoWithInitId_' ".

I would be very pleased if anyone could help me to solve the problem or 
showing me an alternative to implement a GUI in Io.

Greetings, Bernhard
