Hi, I don't know if it's of much help, but it seems your cond-expand is using the fallbavk (-LX11 -L -lGLU), not the windows-specific. Probably because you're not _actually_ on windows.
Perhaps try to edit your opengl.ogg file directly and see if that work. Otherwise, see if you can inject a register-feature! call [1] before the build.
