hypermath.c is indeed written by me. It’s no doubt not as thoroughly tested as 
GLM, so there might be some bugs lurking. So far it has worked well for me, 
though.

Hm, opengl-glew was certainly not written with ES in mind. As far as I know, 
GLEW provides no support for ES. A true OpenGL ES egg (let’s call it opengl-es) 
could likely be very easily made by copying opengl-glew.scm, removing the 
references to GLEW, and creating a gl.h file from 
http://www.khronos.org/registry/gles/api/GLES3/gl31.h via gl-translator.scm 
(the sort of operation that is done in opengl-glew’s setup file). If this were 
done, then it would probably make sense to split gl-math and gl-utils off into 
separate eggs, as well as move the additional definitions made in 
opengl-glew.scm into gl-utils. I’m not sure how you’d get rid of the dependency 
to opengl-glew in gl-utils, though – since presumably you’d want it to depend 
on opengl-es if that were the platform being used. In any case, if this is 
something that you’d like to work on, let me know and we can coordinate our 
efforts.
