You probably want to use include-relative (a macro) rather than
than load-relative.  include and include-relative "load" the
specified files at compile-time rather than run-time; you almost
certainly that rather than load.  load and load-relative don't
really work well with Kawa's compiler-base architecture.
Nor are they defined in R6RS, for the same reason.

load-relative has the further problem of: relative to what?
Relative to the current source file?  There is no current
source file, since load is a run-time procedure.  Relative
to the current working directory?  load already does that.
For load-relative to be different from load, load-relative
(and possibly load) have to have a side-effect of changing
the current working directory.  Having load change the
current working directory seems wrong.  Having load-relative
but not load change the current working directory seems inconsistent.

A clean solution might be to have a separate "current
load path" variable, which gets set by load - and which is only
used by load-relative.  I guess I can do that.

Of course the really cleanest solution is: don't use load
or load-relative.
