Doesn't give much more to go on :P

I wonder what is wrong with the shaders/my system that they aren't compiling?

Here is the first generated shader:

        varying vec3 normal,lightdir,lightposnormalized,halfvector,lightVec;
        varying vec3 blah;
        varying float dist;
        uniform sampler2D tex1,tex2,tex3,tex4,tex5,tex6,tex7;
        uniform sampler2D normalmap;
        uniform sampler2DShadow
shadtex1,shadtex2,shadtex3,shadtex4,shadtex5,shadtex6;


        vec4 fog(vec4 color)
        {
            float z = gl_FragCoord.z / gl_FragCoord.w;
            z = clamp((z-2.0)/5.0,0.0,1.0);
            float oneminusz = 1.0 - z;
            color =
vec4((color[0]*oneminusz)+(1.0*z),(color[1]*oneminusz)+(1.0*z),(color[2]*oneminusz)+(1.0*z),1.0);
            return color;
        }
        vec4 cartoon(vec4 color, int steps)
        {
            float grey = (color.r+color.g+color.g)/3.0;
            float steps2 = float(steps);
            float intensity = float(floor(grey*steps2))/steps2;
            color = vec4(intensity*color.rgb,color.a);
            return color;
        }
        vec4 outline(in vec4 color, in float threshhold, in vec4
setcolor, in float normz)
        {
            if (normz < threshhold) {
                return setcolor;
            }
            return color;
        }
        vec4 tex(sampler2D texture, vec2 uv=gl_TexCoord[0].st)
        {
            return texture2D(texture,uv);
        }

        void main()
        {
            vec3 n = normalize(normal);

            //color
            vec4 color = vec4(0.0,0.0,0.0,1.0);

            //clamp color
            color = clamp(color,0.0,1.0);

            //set color
            gl_FragColor = color;
        }

It's all greek to me, I don't see anything obviously wrong.  It could
be a problem with the pyopengl binding on my system, that's my guess.
I can play the latest of the latest games so I definitely have shader
support.
