I think timing was actually with things off NFS, but for the second
invocation, assuming stuff would normally be cached.

That's the problem.  I normally make sure I don't do that, so I do see
problems with undefined functions and the like.

I'm not sure I understand that, but the usual problem with not
compiling in a clean Emacs is that you have something loaded already
(e.g. cl-macs) which masks the fact that the Lisp in question needs a
require, autoload, or whatever.  That's what I found quite a lot in
Gnus stuff when it was used without most of Gnus loaded.
