It would be good to work up to that. For starters I'm trying to get
examples/ind_def/cl because it doesn't depend on pre-packaging
anything else above the standard library. (float and ieee would need
real and arithmetic and other stuff first.)
I'm having trouble getting even that to work at the moment - I'll
write a separate email why.

No, thanks. My CL webpage (rk436) appears to be working but I haven't
put anything there yet.
