As others have said the undeclared identifier means POV-Ray didn't know 
what that token meant, at the point it saw it, while parsing a texture 
block.

The SDL text posted is confusing to me. I doubt it's aligned well with 
the error message. The texture_list keyword is used only within meshes(1).

I'm pretty sure a texture_list {...} hanging in space won't itself 
parse. I don't know how we reached the token, Material_051, if this the 
SDL text causing the error.

Hmm, I guess it all could be inside a mesh/mesh2 block not shown, but 
declaring MAT_Material_034 inline/on the fly within a mesh like that 
would be odd - if such a thing works at all.

(1) There is a concept of TEXTURE_LIST which gets used with block 
patterns as in:

#declare TextureChecker = texture {
     checker
     texture { Tred }
     texture { Tgreen }
     scale 0.2
     warp {turbulence 0.5}
}
