Xlib: extension "GLX" missing on display ":1.0".
Do you have GLX compatible drivers on this maschine, is GLX activated in your XF86Conig file? I often forget these trivial things...
I don't know but I thought that ./configure would pick up everything I have or not and react accordingly. It's bad if the install fails before it's even finished. What's GLX? It's not mentioned in my XF86Config and locate GLX only produced two man entries. My graphic card is a Diamond Stealth 64 PCI.
This is a warning produced by X itself because Wine tries to use GLX at start-up to probe for OpenGL support.
This is completely harmless.
