Not quite.  The original versions of some stuff from the library hung
around, and my efforts to delete them led to more difficulties.

Specifically, after loading the library I deleted the names of the
generics and classes from the library's frame.  Then I read the source
files into the frame.  This time it complained there was no function by
the appropriate name when I tried to do setMethod, even though the
previous file should have created it.
