"guix package --search-paths" should do that.  The only obstacle I see
in evaluating this automatically in profiles is that same variables are
not merged automatically, e.g. PYTHONPATH for different versions of
Python.

This is done on the package level.  LV2 audio plugins, for example,
suggest the LV2_PATH variable to be set.  For Ruby this could be done
by the build system.
