I report I was able to build Larceny revision 6186 and these do now
work:

Autoloading (sweet-macros helper2)

I prefer using Larceny to build itself.  A Scheme system should build
itself.  (But being able to be built by others is neat too.)

If Larceny came prepackaged, it would be equally easy to use for
building new Larcenys.  I know those Linux distribution packaging people
love to add new packages as quickly as they can.
