I'm not sure they're JUST formatting errors. I worked for quite a while
on that file, and still haven't gotten it to work satifactorily. One of
the things that is NOT a formatting error is a function which is no
longer included past V. 3 of Mathematica: SingularValues. As far as I
can tell, this is replaced by the newer SingularValueList.

  In any case, I'd love it if someone manages to get that package
working and posts it!

           Cheers,
