the list is ‘guile-user’ without the s. 

http://lists.gnu.org/archive/html/guile-user

I'll close this bug.

you may have installed the new version of Guile side to side with the old one —that's normally a good thing to do if the system depends on the old one. But you need to know where you've put the new version. What do you get from ‘which guile’ and ‘which guile-config’?

GLX and EGL are libraries to open OpenGL contexts. guile-opengl is a separate library (that doesn't come with Guile by default) and that provides bindings to GLX from Guile itself.

But Ao doesn't use guile-opengl, it uses GLFW, which is a C library. I'm guessing there's something going on with your drivers. If you search for ‘Couldn't find current GLX or EGL context’ you'll find this report:

Hope this helps.

Hello,

For the record, there’s an Ao package in Guix.  If you don’t use Guix,
looking at the package’s recipe might still be helpful to figure out how
to run it.
