Let me guess : You are linking with IrisGL libraries, while compiling without
the -DIRISGL compilation flag. Performer/pr.h includes irisgl.h or opengl.h,
depending on that compilation constant (the default is OpenGL). If you follow
the PFLT_DIFFUSE constant in opengl.h, you'll see that they use the GL_DIFFUSE
constant from GL/gl.h, which is 4610.
To make a (very) long story short, you should define IRISGL in all your
compilations (unless you want to use OpenGL). To keep my makefile simple, I
have an environment variable - PF_GL, which is initialized to either IRISGL or
OPENGL at login, and is used by the makefiles.
